Two large conducting spheres carrying charges and
are kept with their centres r distance apart. The magnitude of electrostatic force between them is not exactly
because
Option: 1 these are not point charges.
Option: 2 charge distribution on the spheres is not uniform.
Option: 3 charges on spheres will shift towards the centres of their respective spheres.
Option: 4 charges will shift towards the portions of the spheres which are closer and facing towards each other.
The magnitude of electrostatic force between them is not exactly because the charge distribution on the sphere is not uniform
