A charged particle moves in a gravity free space

Asked by admin @ 17/08/2021 in Physics viewed by 297 People

A charged particle moves in a gravity-free space without change in velocity. Which of the following is/are possible?

(a) E = 0, B = 0
(b) E = 0, B ≠ 0
(c) E ≠ 0, B = 0
(d) E ≠ 0, B ≠ 0

Answered by admin @ 17/08/2021

The possible actions are (a), (b) and (d).

Explanation:

In a gravity-free space, a charged particle can move without any velocity change in the below three ways:
(1) B = 0, E = 0, that is, on the particle, no force is acting and later, with a constant velocity, it moves.
(2) E = 0, B ≠â€‹ 0. Along the direction of the velocity v, if there is a magnetic field, then the force will be zero. So, there is no acceleration of the particle.
(3) Due to the magnetic field, if the force due to electric field balancing each other, then on the particle, the net force acting will be zero. Hence, there will be a constant velocity on the particle.
