Answer:
Let T is the tension acting on the string. If T is resolved into vertical and horizontal components, vertical component balances the weight of the ball and horizontal componenet provides centripetal force. Let ω be the angular velocity
mg = T cosθ .................(1)
mω2r = T sin θ ........................(2)
Divide (2) by (1) to get tanθ = ω2r/g = r/h
Hence
