Given below are two statements : One is labelled as Assertion (A) and the other is labelled as Reason (R).Assertion (A) : In an uniform magnetic field, speed and energy remains the same for a moving charged particle.
Reason (R) : Moving charged particle experiences magnetic force perpendicular to its direction of motion.
Official answer
(1)
Both (A) and (R) are true and (R) is the correct explanation of (A).
