The centripetal acceleration is defined as proportional to v^2 and inversely proportional to r.
a = v^2 / r
Once you have this you can apply Newton's second law to find centripetal force.

When abody moves with constant speed 'v' on a circular path of radius 'r', its acceleration is directed towards the center and known as centripetal acceleration
Centripetal accleration= v^2 / r
=20*20 / 19 =21.05 meter per second square
Centripetal force=mass* accleration=36*20*20 / 19=757.89 newton
