Q: A neutron, a proton and an electron are placed in a uniform electric field.
(A) The forces acting on them will be equal.
(B) Their accelerations may be equal.
(C) Magnitude of acceleration may be equal.
(D) Magnitude of acceleration will be different.
Solution :Force on neutron = 0 (as charge = 0)
Force on proton = qE
Force on electron = qE
Masses of proton and electron are different.
Hence their accelerations will be different.
Hence (D) is correct.
