A proton and an electron are placed in a uniform electric field.

A

The magnitude of the electric forces acting on them will be equal

B

The electric forces acting on them will be unequal

C

The magnitude of their accelerations will be equal

D

Their accelrations will be equal

Text Solution

Verified by Experts

The correct Answer is:
A

As `F = qE, E` is uniform and also , `q_("proton") = q_("electron")` therefore,magnitude of electric forces will be equal. This is the only correct choice.
