Two blocks A and B of mass m and 2m respectively are connected by a massless spring of spring constant K. This system lies over a smooth horizontal surface. At t=0 the block A has velocity u towards right as shown while the speed of block B is zero, and the length of spring is equal to its natural length at that instant. In each situation of column-I certain statements are given and corresponding results are given in column-II. Match the statements in column-I corresponding results in column-II
Column-I Column-II
A) The velocity of block A P) Can never be zero
B) The velocity of block B Q) May be zero at certain instants of time
C) The kinetic energy of system of two blocks spring R) is minimum at maximum compression of spring
D) The potential energy of spring S) Is maximum at maximum extension spring
