1. The electric potential at a point on the axis of a ring of charge of radius R=3 m is

v = 1/4Πε₀ Q/ √z² + R²

Q = 125 nC. If a point charge q = 15 nC is located at z = 4 m, find the net force exerted on the charged particle by the ring.

2. Two concentric spheres of radius R₁= 3 m and R₂ = 6 m are shown below. Each charge has a charge Q = 9 nC.
