A dielectric slab with thickness $d$ and dielectric constant $\kappa=2.31$ is inserted in a parallel place capacitor that has been charged by a $110 .-\mathrm{V}$ battery and has area $A=100 . \mathrm{cm}^{2}$ and separation distance $d=2.50 \mathrm{~cm} .$ a) Find the capacitance, $C$, the potential difference, $V$, the electric field, $E$, the total charge stored on the capacitor $Q$, and electric potential energy stored in the capacitor, $U$, before the dielectric material is inserted. b) Find $C, V, E, Q,$ and $U$ when the dielectric slab has been inserted and the battery is still connected. c) Find $C, V, E, Q,$ and $U$ when the dielectric slab is in place and the battery is disconnected.

As we all know that the value of I. T. Is equal to B E M F by our multiplication E. To the power minority by R C one. Simplifying it further, I can write the value of C is equal to -30 by are long I uh by B E m F. Going forward and putting the value in this expression so I can write the value of C is equal to -1.743 by 655.1. Multiplication alone .1745. Multiplication 655.1 by 133.1. On solving it further, I can write the value of C is equal to -1.743 By 655 .1 multiplication -152 on further simplification, I gained the value of C ad 17.5, multiplication 10 to depart minus three F. Changing the unit, I just multiplied by one MF by 10 to depart minus three F. On. Further simply because an idea of the value of chf 17.5 M f. I D. Capacitance.

Houston a capacitor. He just Galveston's of see it's charged by potential me and disconnected and then and it Plus two child given on positive plate june on a budget to that. So firstly let the initials are on the happiest and B. H. Q. Mhm This is you And this is my next pure okay this Lescure and this is my next year. So we have you're not Egypt was to see so now john Q. Is given who? For the two plate and new potential new potential 14 shell three days is equal to A. B equals two Even less e. two. And deep this is new potential and you had even yeah even and he too all the day mm filled. Mhm. In the yeah due to job judge Q plus Q. And Q minus Q minus Q. No. So charges you. Bless you not. And my next spring so yeah We have calculated even equals two few less. You not the right way two. Excellent. Not because we know that formula is it was too Q. To our silent no. Today. Okay. And he two equals 2. The music was too you not the weird way to silent mode. We put the values even and two in this formula then does we get Pull the values and read a Z. equals two Q plus Q. Not the right way to excel. And not a less. You not divide by two. Excellent. Not a into the after solving we get you do you have to buy to sell a note A. Bless you not be do you ride by a silent hey So three days is equals two Killed by two seats. Plus we. This is our final answer because this is the potential new potential on campus triplet. Okay. Thank you.

First, we have three coupon tree. Yeah. Uh, let the capacities of each capacity B C. Therefore judges Cuban is C V. Q two is C V and Q three is see the um, therefore Q one is equal. Look, you two is equal to Q three is equal to Q. Therefore, Q total is equal to three Q. One. So there is Cuban. Is it going to kill upon three? No, Um, and second one we are given. C is equal to 0.25 Micro battered that is the color of their 0.25 and 2 10 to the four minus six carats. We is 12 volt. Therefore, Q one is equal to Q two is equal to Q three is equal to C V. There is there a point to 5 to 10 to department six fathers multiplied by 12 balls. There is a girl to three and 2 10 to the power minus six cooler, that is three Micro column No, the third one charges Judge drawn from judge. Drawn from the battery is Q one plus Q two plus Q three. There is three plus three plus three micro column that is nine micro

In this question you have a parody update capacitor. Okay, So it's connected to a six volt battery. Right? So in this case what we have over here is uh huh. Initial energy start in 72 zero Nano Jews. Then after you insert the dielectric. Yeah. Oh yeah. Okay. Uh I'll tell you is equal to 317 you know jews. Okay. So therefore passing this question, we want to find a dielectric constant. The charge on the please after the dielectric is inserted and uh mental the feud between the plates before and after the electric is inserted. Okay, so to do by a find a dielectric constant. Okay so we know that. Yeah dielectric. Okay see prime is kappa psi not your prime is uh huh. Have c prime be square which is half coppa seen on you're square. And it's this papa you know, okay, time you're not are you i is equal to 72, you know Jews, are you crying is equal to 72 plus 3 +17 Which is China 89 9 of Juice. And copy it would just be your prime over. You know Which is China 89 divided by 72. And then you get 5.40. Okay, so this is a dielectric constant. Okay. And part B. We need to find out charge saw on the uh capacitor after the directory. Who has been inserted? So you're using U. Equals to have QB. Mhm. So Q. Would just be too you divide by B. Because here you, is there Your prime in primate? A. So two times 3 89. Uh You know, jews get by by six words and you get 130, you know, columns. Okay, so this is the answer for puppy. The next I see you want to find a electrocute before the dielectric has been inserted so we can find this ah Finding A Cure 1st. Before the dielectric, wow. Uh is inserted. Okay to not this to you. Not divide by B. Just two times 70-90 jewels. Given by six votes. And you get 24 and columns. Okay. So for paralympic, What parallel pain arrangement? Two yes. Equal to sigma or X. Or not? Which is Q. Over A. X. Or not? So and since we have given the area we can compete directly. So 24 times 10 to the -9. Goodbye. Barry. 50 times 10 to the -4. 8.5 times center to limit yourself. He and you probably do as you get 5.42. Thanks 10 to the five votes power meter. Yeah. Okay so this is the answer for Patsy. He for paddy. Want to calculate the E. The electric field after the dielectric is inserted. So I think so. Capacitor, he's still connected to the veggie after the battery is inserted. E after Is equal to e. four. Okay. And you get 5.52. Thanks 10- five. Sports car. Uh huh. So this is the answer for paddy. Mm. That's all for this question.
