A charge polished metal sphere has a radius of 15 cm. The insulation of the air breaks down when the electric field near the surface of the sphere reaches 2.5x10° V m. Assuming that the charge on the sphere acts as if it were all situated at the centre. Calculate the maximum charge and the maximum potential for this sphere.
