Electrostatic Potential And Capacitance

Question

Wired Faculty App

Answer carefully:
a) Two large conducting spheres carrying charges Q₁ and Q₂ are brought close to each other. Is the magnitude of electrostatic force between them exactly given by Q₁ Q₂ /4 $π$ ε₀r², where r is the distance between their centres?

Solution

The charges are not exactly point charges in this case. And since, the large conducting spheres have been brought closer, the charge distribution will no longer remain uniform. Thus, the magnitude of electrostatic force between the two spheres cannot be given by

\frac{Q_{1} Q_{2}}{4 {πε}_{\circ} r^{2}}
