The surface density on a copper sphere is sigma . The electric field strength on the surface of the sphere is

Two parallel large thin metal sheets have equal surface densities 26 xx 10^(-12) C//m^2 of opposite signs. The electric field between these sheets is -

Two infinite plane parallel sheets, separated by a distance d have equal and opposite uniform charge densities sigma . Electric field at a point between the sheets is

If three infinite charged sheets of uniform surface charge densities sigma, 2sigma and -4 sigma are placed as shown in figure, then find out electric field intensities at points A, B, C and D.

A spherical charged conductor has sigma as the surface density of charge. The electric field on its surface is E. If the radius of the sphere is doubled keeping the surface density of charge unchanged, what will be the electric field on the surface of the new sphere -
