A hollow metal sphere of radius 15cm is charged such that potential on its surface is 20 V, then the potential at the centre of sphere is

what is the electrical potential at the center of a charge carrying sphere

A solid conducting sphere of radius R is charged such that the magnitude of the electric field at the surface of the sphere is 4.239 ⋅ 105 V/m4.239 · 105 V/m . The potential 28.37 cm from the surface of the sphere is 6.288E5 V. What is the radius R of the sphere?

What voltage 4.5 cm away from the center of a metal sphere of radius 3.5 cm would produce a static charge of 2.2 μC?

An uncharged nonconductive hollow sphere of radius 17 cm surrounds a 14 µC charge located at the origin of a cartesian coordinate system. A drill with a radius of 1.00 mm is aligned along the z axis, and a hole is drilled in the sphere. Calculate the electric flux through the hole. (units of N m2/C)

Find potential outside and inside of a uniformly charge (q) sphere of radius R. Also, plot V as afunction of distance.
