1.	Find the minimum height of the obstacle so, that the sphere can stay in equilibrium.
Answer» `R/(1+costheta)` `R/(1+sintheta)` `R(1-sintheta)` `R(1-costheta)` Solution :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`
