A uniformly charged spherical conductor has a radius of 1m and surface charge density 0.8Cm2. The electric field magnitude because of this at a point 1m radially away, from the surface of the sphere is
A spherical charged conductor has a surface charge density σ. The electric field on its surface is E and electric potential of the conductor is V. Now the radius of the sphere is halved keeping the charge to be constant. The new values of electric field and potential would be
