Electrostatics (Doubt)

Consider two conducting spheres of same radius $$r$$, separated by a distance $$d$$. Charges $$+q$$ and $$-q$$ are placed on the two spheres. Find the force $$F$$ acting on one sphere due to the other.

Consider the charge centred at the centre. Force sud be q^2/(d+2r)^2

I am guessing. Am I right?

No. The spheres are conducting. Hence, the charges distribute in such a way that the potential at the surface is equal radially symmetric.

@Kishore S Sheno Nope, I don't know the answer.

@Kishore S Shenoy The separation is arbitary (of course, greater than 2r).

@Kishore S Shenoy There are two spherical conductors : one having charge +q and other -q. Find force of interaction between them ( as a function of their common radius r and distance between their centres d).

Ohh, the separation is not large? I suppose that is the catch?

Can you please elaborate the question?
