Answer:
plz mark me brainliest.
Explanation:
it moves in a circular path
its velcoity is constant
its acceleration is constant
its kinetic energy is constant
Answer :
A::D
Solution :
When force of constant magnitude is perpendicular to the velcoity of the particle, motion is along a circular path. Direction of velocity / acc. goes on changing , but KE=12mυ2= constant.
