A charge Q is kept in front of a neutral metallic sphere,find the electric field at the centre of the sphere due to induced charges on the surface of the sphere. Share with your friends Share 13 Ved Prakash Lakhera answered this Let us consider Gaussian surface of radius d from the centreof of the sphere.According to Gauss's law E×4πd2=qε0or E=q4πε0d2Thus the electric field at point O along x-axis=Ex =Ei^=q4πε0d2i^.The correct option is 1 q4πε0d2i^. 3 View Full Answer
