If a block is kept on a wedge,wedge is moving in negative x direction with an accleration of A.then for what minimum value of A the block starts falling freely.if required assume the mass of block m and the mass of wedge M.yeah surface is frictionless.here we'r required to find out the minimum value of the accleration of the wedge that is assumed A.the wedge angle is theta.actually this problem is from dc pandey.in objective tab it is given.i solved the question but not getting the answer.pls u analyse the situation and get me the detailed solution or just hint.plsplspls....

hey ...,,,its easy get your concepts of pseudo force clear...

look the min acc/n is such that it balances the the normal reaction

therefore :

 mgcos(theta) = mA sin (theta)

a = gcot(theta)
