Question:

A charged particle moving with a certain velocity enters a uniform electric field perpendicular to its direction. In this context, which of the following statements are correct?

(A) Force acting on the particle is constant
(B) Acceleration of the particle is constant
(C) Velocity of the particle is constant
(D) Displacement of the particle follows a parabolic path

Choose the correct answer from the options given below:

Options:

(A), (B) and (C) only

(A), (B) and (D) only

(A), (B), (C) and (D)

(B), (C) and (D) only

Correct Answer:

(A), (B) and (D) only

Explanation:

The correct answer is Option (2) → (A), (B) and (D) only

(A) Correct — Force on a charged particle in a uniform electric field $F = qE$, constant in magnitude and direction.

(B) Correct — Acceleration $a = F/m = qE/m$, constant since F is constant.

(C) Incorrect — Velocity changes due to constant acceleration; only the component along the field increases.

(D) Correct — Motion under constant perpendicular acceleration results in a parabolic trajectory.

Correct statements: (A), (B), (D)
