Question

(a)

Work done by magnetic force will always be zero as $\vec{F} \perp \bar{V}$ so using work energy theorem

$W_{	ext {all }}=\Delta K$

$W=0$

Vedclass · Accepted Answer

Energy remains constant but momentum changes

Vedclass · Answer

(a)

Work done by magnetic force will always be zero as $\vec{F} \perp \bar{V}$ so using work energy theorem

$W_{	ext {all }}=\Delta K$

$W=0$

$\Rightarrow k=	ext { constant }$

$\vec{P}$ change as direction of velocity changes.
