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.
