We have an isolated conducting spherical shell of radius 10 cm . Some positive charge is given to it so that the resulting electric field has a maximum intensity of 1.8 xx 10^6 NC^-1 . The same amount of negative charge is given to another isolated conducting spherical shell of radius 20 cm . Now, the first shell is placed inside the second so that both are concentric as shown in (Fig. 3.154). . The electric field intensity just inside the outer sphere.
