Answer:
The centripetal acceleration of the object is
.
Explanation:
We have,
Radius of a circular path is 200 m
It takes 5 seconds to complete 10 revolutions. The angular velocity of the object is given by the rate of change of angular displacement per unit time :

The centripetal acceleration of the object is given by :

So, the centripetal acceleration of the object is
.
