A charge of 1.50 * 10-8 C lies on an isolated metal sphere of radius 16.0 cm.With V = 0 at infinity, what is the electric potential at points on the sphere’s surface?

A positive charge is evenly distributed on the surface of a metal sphere centered at the origin of the coordinate system. The positive charge produces an electric field that points outwardly in the radial direction. A positive test charge is fixed at a distance R₁ from the center of the coordinate system, far from the surface of the sphere. The electric potential at R₁ is 10V. The positive test charge is then allowed to move freely until it reaches a distance R₂=2R₁ from the center of the coordinate system. What is the electric potential (in Volts) of the test charge at its new resting point? 10

A metal sphere with radius 1.10 cm is supported on an insulating stand at the center of a hollow, metal, spherical shell with radius rb = 9.10 cm. Charge +q is put on the inner sphere and charge −q on the outer spherical shell. The magnitude of q is chosen to make the potential difference between the spheres 400 V, with the inner sphere at higher potential. Calculate q. Express your answer in coulombs. q=__C
