Question

An isolated, irregularly shaped piece of platinum carries -8.39 times 10^-9 C of charge and is in electric equilibrium. The size of this body is about 4 mm. When the electric potential at some point on the metal's surface has the value V, the potential at a different point on the surface (indicate one): always differs from V. equals V. may equal V. When the electric field strength at some point on the body's surface has the value E. the field strength at a different point on the surface (indicate one): equals E. equals 0. may equal E. always differs from E. Calculate the potential at a distance of 5.63 m from the centre of the charged piece of platinum.
