Solution

The correct option is A Its momentum changes, total energy is same
The magnetic force will act perpendicular to velocity at every instant ,path will be circle. Due to change in direction momentum will change but the total energy will remain same.

Q. Assertion :When a body is moving uniformly in a circle, its momentum goes on changing continuously but its kinetic energy remains constant. Reason: Momentum

p = m v

but K.E.=

0.5 m v^{2}

. In uniform circular motion

v

changes but

v^{2}

does not change.
