A thin spherical shell encloses a concentric solid sphere. The radius of the shell is (0.060)^((1)/(2)) m and its surface charge density is -10^(-6)C//m^(2) . The radius of the solid sphere is (0.01)^((1)/(3))m and its volumetric charge density is 3 xx 10^(-5)C//m^(3). epsi_(0) is the permittivity of free space in C^(2)//Nm^(2) . The electric flux through a spherical surface concentric with the spherical shell and of radius greater than that of the shell in V-m is
