Consider two concentric spherical shells, one with radius R, and with the radius 2R. Both have the same charge Q. At a point just inside the outershell, the magnitude of the electric field is
According to Gauss law the electricflux emanated out of a closed surface be equal to the ...
The magnitude of electric field at point just inside outer shells are determined. The outer spheres are analyzed. The solution clearly shows the formulas used in solving the problem.
