Question

Please help me break down and work through this practice question so that I can better under the steps and work it out on my own.

6. A proton and an electron are separately placed at rest in the same uniform electric field. What can be said about the motion of each? A) Both remain stationary. B) Both move in the direction of the electric field. C) Both move in the opposite direction of the electric field. D) The proton moves in the direction of the electric field, the electron moves in the opposite direction. E) The electron moves in the direction of the electric field, the proton moves in the opposite direction.

Answer 1

solution Oh In In order order to work it on your own, you must the concept. I will try my best. so first of all, whenever a charged particle is present is an electric field, it experiences a electric force, so if charged particle is positive, z > F-qe Force is along the direction of eleemic field. If charged particle is negative, F=qE Force is in the derection opposite to the direction of Electric field. This force creates acceleration as F- ma and lets the charged particle move in the specified direction, lets proceed to the question, solution 6 We have a proton which is positively charged - with charge (te) and an election which is negatively charged with charge (-e)

Now (A) Obviously, none of them can't be stationary as well explained above. It is False. (13) me since charges on profon & election are of opposite hatwee, hence they can't move in the same direction either towards or opposite to the direction of Electric field. This is False. © As explacried in (B), false. it is also (D.) Proton is positively charged, moves in derection of Electric field as fore is in same diration. Election is negatively charged, moves in the opposite defection of Electric field was force is in the opposite direction . Hence this is TRUE. 6. Obviously, D is the sught one, this is naturally FALSE again . Hope you like my efforts and my solution.
