In the above problem, find the electric field and electric potential at the centre of the sphere due to induced charges on the sphere?

A charge q kept in front of a neutral metallic sphere. Find the electric field at the centre of sphere due to the induced charges on the surface of the sphere shown. Strategy : The net electric field inside the conductor is zero. This is produced by induced charges and the external charge.

Electric field due to spheres

Consider a metallic hollow sphere with its centre at point O. Point charge +Q is kept in the vicinity of the given sphere as shown in the figure. If the sphere is electrically neutral, then calculate the electric potential at point A due to induced charges on the sphere only.

STATEMENT -1 : Consider a conducting sphere of radius R . Now a charge q is placed in front of shphere . Electric potential at point O is (Kq)/r STATEMENT -2: Electric potential at the centre of sphere due to induced charges is zero.
