PhysicsElectrostatic Potential and CapacitanceNEET 2012

Two metallic spheres of radii and are given charges of and , respectively. If these are connected by a conducting wire, the final charge on the bigger sphere is

Answer: (3)

Solution

When the spheres are joined by a wire, charge flows until both are at the same potential . Total charge is conserved: . Capacitance of an isolated sphere is , so common potential $V =
