Two large conducting spheres carrying chargesQ_{1} and Q_{2} are kept with their centres r distance apart. The magnitude of electrostatic force between them is not exactly \frac{1}{4 \pi \varepsilon _{0}}\frac{Q_{1}Q_{2}}{r^2} 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.
