Find minimum height of the obstacle so that the sphere can stay in equilibrium

A

`R/(1+costheta)`

B

`R/(1+sintheta)`

C

`R(1-sintheta)`

D

`R(1-costheta)`

Text Solution

Verified by Experts

The correct Answer is:
D
The sphere is on the verge of toppling when a line a action of weight passes through the edge.
`costheta=(R-h)/Rimplies h=R-Rcostheta`
