JEE MainPhysicsElectrostaticsMCQ+4 / −1

Two identical conducting spheres A and B, carry equal charge. They are separated by a distance much larger than their diameters, and the force between theis F. A third identical conducting sphere, C, is uncharged. Sphere C is first touhed to A, then to B, and then removed. As a result, the force between A and B would be equal to :

A
F
B
${{3F} \over 4}$
C
${{3F} \over 8}$
D
${{F} \over 2}$
