STATEMENT - 1: A charged particle is moving in a circular path under the action of a uniform magnetic field as shown in the figure. During motion kinetic energy of charged particle is constant. STATEMENT-2 : During the motion magnetic force acting on the particle is perpendicular to instantaneous velocity.

Options

  1. AStatement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.
  2. BStatement - 1 is True, Statement - 2 is True; Statement - 2 is NOT a correct explanation for Statement - 1.
  3. CStatement - 1 is True, Statement - 2 is False.
  4. DStatement - 1 is False, Statement - 2 is True.

Correct answer

A. Statement - 1 is True, Statement - 2 is True; Statement - 2 is a correct explanation for Statement - 1.

Step-by-step solution

( aligned & F = q ~V B & ~F ~V aligned ) So power produced by magnetic force is zero.
