Question #04d86

Answer 1

200 #ms^-2 #

Explanation:

Centripetal acceleration of a body revolving in a circular orbit is always directed towards the center of the circle.

If v is the velocity of the body and r is the radius of the circular path then the centripetal acceleration is given by `v^2/r`

Substituting the values of velocity and radius of the circular path

we got `20^2/2`

`=>400/2=>200ms^-2`
