`-10mu C, 40 mu C` and q are the charges on three identical conductors P,Q and R respectively, Now P and Q attract each other with a force F when they are separated by a distance d. Now P and Q are made in contact with each other and then separated . Again Q and R are touched and they are separated by a distance 'd' . The repulsive force between Q and R is 4F . Then the charge q is:

A

`10 mu C`

B

`30 mu C`

C

`40 mu C`

D

`65 mu C`
