Question

If a particle is moving on a circular path with constant speed, then the angle between the direction of acceleration
and its position vector w.rit. centre of circle will be
(1) Zero
TC
(2)pi/2
(3)pi
(4)2pi​

Answer 1

Answer:π/2

Explanation:

Since angle b/w centripetal force and velocity is π/2 so the angle b/w centripetal acc. And position vector is π/2

Answer 2

The position vector directs towards east, the centripetal force directs west. So angle between the two vectors is 180°= π
