Question

A body is moving in a circular path with
acceleration If its velocity gets doubled
then to find the ratio of acceleration
after and before the change of Velocity? ]​

Answer 1

The ratio is 4

Explanation:

When a body moves in a circle , the centripetal force is developed . That means body is accelerating due to change of direction .

The acceleration of the body  a₁ = v²/r

here v is the velocity of the body and r is the radius of circle of motion.

When the velocity is doubled , the acceleration a₂ = ( 2 v )²/r = 4 v²/r

The ratio of two accelerations a₂/a₁ = 4
