Ram is preparing for IIT JEE. He sets on to tackle a typical problem in mechanics. He sees that the wedge is kept on a smooth ground and it's inclined surface is also smooth. A block is projected on it as shown. Both the block and wedge have equal mass. Can you help him find the answer to following three question? What is the radius of curvature of it's path at the highest point?

Answer»

0
`(v_(0)^(2)cos^(2)THETA)/(G(sinthetacostheta+sin^(2)theta))`
`(v_(0)^(2)cos^(2)theta)/(2g(1+sin^(2)theta))`
NONE of these

Solution :`(v_(0)^(2)cos^(2)theta(1+sin^(2)theta))/(8gsin^(2)theta)`
