what happens to V ?

None

When the separation between thye two charges is increased, their potential energies will increase or decrease or remains same ? why

their mutual potential energy decreases because

U= kqq/r

but the self energy remains the same.....

There is no significance of the potential energies of the individual charges.

Depending upon the nature of the two charges (same or opposite) the potential energy of the system will vary.

if the charges are of opposite sign then on increasing the separation the PE of the system will decrease and of the charges are of the same sign then the PE of the system will increase.

johri is right potentiol difference=q1q2/4pie epsilon r
if the signs r opposite then the v increases but if they r of same same sign then the v increases
