COLUMN-I		COLUMN-II
A)	$\underset{•}{+q}\underset{•}{-q}$ (Point charges)	P)	Kinetic energy of system increases
B)	(where $P_1$ is short dipole and q is point charge)	Q)	Electric potential energy of system decreases
C)	(where  $P_1$and$P_2$ are short dipoles)	R)	Linear momentum of system remains conserved
D)	Uniformly charged ring having positive charge and a dipole P is placed Symmetrically and lying along axis of ring placed at a distance less than  $\frac{R}{\sqrt{2}}$ from the centre of the ring	S)	Separation between elements of system increases (in case of dipole and ring separation to be measured from centre
		T)	Separation between elements of system decrease (in case of dipole and ring separation to be measured from centre)

In the column -I a system of two charges/dipole/other charges are released (released from rest) in gravity free space. They move due to their mutual electrostatic interaction only. In column-II change in some physical quantities in the system is mentioned for some time interval in which no one reverses its direction nor they collide. Match the situations correctly
