Q. Two blocks of equal mass have been placed on two faces of a fixed wedge as shown in figure. The blocks are released from position where centre of one block is at a height above the centre of the other block. Find the time after which the centre of the two blocks will be at same horizontal level. There is no friction anywhere.
