Two conducting shell (massless) fixed on insulating stand are separated by distance L (center to center) in vacuum One of them is charged with +Q and other with - Q What is the force of interaction between them??
K(Q/L)^2
More than K(Q/L) ^2
depends upon the temperature
less than K(Q/L) ^2

The charge on one shell will cause the charges to be induced in the other shell which will again cause some Induction in first shell and the process would go on..the expression of force can be obtained using method of images to the precision as required.. . Surely it will be greater than K(Q/L) ^2
