The force on a charged particle due to electric and magnetic fields is given by $\vec{F}=q \vec{E}+q \vec{v} \times \vec{B}$. Suppose $\vec{E}$ is along the $X$ -axis and $\vec{B}$ along the $Y$ -axis. In what direction and with what minimum speed $v$ should a positively charged particle be sent so that the net force on it is zero ?

Belongs to the magnetic fields in which we have a uniform magnetic field that points vertically upward. Okay, vertically, upward we have a magnetic field. And in what direction should a positive charge charge is here, positive should move. That is the velocity vector we have to determine so that it experiences a magnetic force. So for the part of the magnetic force in the north direction, Okay, so let us suppose This is the direction of the 4th, in the North Direction, and magnetic field is here in the upward direction. So we can deter right is at dot. So it means from the right anthem rule, we can determine that the particle must move in the west directions. This will be the velocity of the direct particle, so we can write that. The answer for this part is west. Okay. And similarly for the part B, the force is in the east direction. So this is the direction of force. And magnetic field is given as in the daughter directions. So it means from the right and to rule, we can obtain that the particle much to move in the north direction. Okay? So that it experiences force in the each direction, so answer for the party B comes out to be north. Okay, So these are the two answers for the questions. Okay? These are obtained from the right hand thumb rule, right hand thumb rule. Okay? Using this rule, we can obtain the results.

In this problem, as we all know that he is equal to U. Plus 80 the speed of particle will be minimum when he is equal to zero, so is equal to minus Q. E. Bye And substituting this value in the application I can write in zero is equal to we, not scientific data minus E by M. Multiplication T. The value of is equal to and maybe not scientist by you to eat so according to the option in this problem, Option B. It's correct answer. Option B. H. Correct answer for this problem.

All right, guys, get into the question. So charged particles of projected into a region where there was a magnetic field popping decolletage. Velocities. If the particles are deflected in opposites directions, what's going you see about them? So to to charge part schools trying popularly glow. So a magnetic field. So we have in this sense I'm gonna use to migrants. You have the first magnets, which is just not full and sickle magnets just showing the salt poll. Oh, a linear increase between the nuggets. Yeah. So you have the north pole of our first magnets in the north Pole of circle magnets. Do you have? Ah, magnetic field going from notes for the South Pole, but not to the salt Full? Yeah. You know the direction just to show the movements of the magnetic field? Yeah. Oh, yeah. So we have to charred or schools. They might be on the same charge or limit negative charge. Indoor worlds, you see, sees the If the particles are deflected in opposite directions, what can you see about them? Policy for understand this part? Schools come towards or get into the magnetic field or the comic contacted magnetic field and just named. Just name this a and be so if, though, if particle a goes to this direction and parts will be goes to the direction, what's can you see about them off? The answer would be on. These two particles are opposite charges because if they were to have gone in the same direction, so let's say, for instance, be wins interruption of a instead off going to this up with the direction we can see the A M B have the same on the same charge boards A went in this direction. It went left and being with right after coming contact with magnetic field. So therefore, the health might be have different charges for clarity. I would state that own they have over the charges and the direction of the force on the charge Part school depends on the type of the charge. So if the magnetic field pushes the chart board, school lift or pushes, it writes, it should have to depend on the charging cars basically. So the magnetic forces calculated why isn't off course products that is dependent on the type of charge. So regardless of whatever happened or what up of charge, Jerry's there must be some type of reaction or forced. It's passed on to the particles that make them to move in a specific, especially direction or deflection. So in this sense, a moved left and be moved right. So these two parts schools are opposite charges. Beautiful fact that they deflected in opposite directions.

Hi in this given problem there is a magnetic field which is directed due East. Yeah. As shown in this bigger this is the magnetic really. Let it be be bar and there is a negative charge suppose the charge carried by it S. Q. And it is moving it is also moving Due East suppose with a velocity we bar. So magnetic Lawrence force experienced by the negative charge which is moving parallel to the magnetic field is given by F is equal to minus Q. Into we across B. Which is also given us in magnitude minus Q. We be Sign 0° because the velocity vector and magnetic reflector are in the same direction. So angle between them is 0°P. It will come out to be zero. So we conclude this negative charge moving parallel to the magnetic field. Yeah. Does not experience any force. Thank you.
