Answer:
Explanation:
Given
Sphere of Radius R
Suppose mass of block is m
At any instant \theta Normal reaction(N) and weight(mg) is acting such that
, where v is velocity of block at any angle \theta
When block is just about to leave then N=0
therefore
-------------------1
Also by conserving Energy we get
Potential Energy=kinetic Energy of block
here h=vertical distance traveled by block
From diagram
-----------------2
From 1 and 2
Thus from this value of h is
