A Conducting Sphere of Radius R₁ = 10 Cm and Charge

Multiple Choice

A conducting sphere of radius r₁ = 10 cm and charge q₁ = 2 C is placed far apart from a second conducting sphere of radius r₂ = 30 cm and charge q₂ = 3 C.The two spheres are then connected by a thin conducting wire.What is the potential on the surface of the first sphere after the two spheres are connected by the wire? Use the reference V = 0 for r at infinity.
