JEE MainPhysicsMagneticsMCQ+4 / −1

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.

A
Both (A) and (R) are true and (R) is the correct explanation of (A).
B
Both (A) and (R) are true but (R) is NOT the correct explanation of (A).
C
(A) is true but (R) is false.
D
(A) is false but (R) is true.
