The ratio of flux through s2 and flux through s1 is K’ . Then find the value of 9K’/11.

S1 and S2 are two hollow concentric spheres with charge q and 2q . space between s1 and s2 is filled with a dielectric of dielectric constant K = 5 . The ratio of flux through s2 and flux through s1 is K’ . Then find the value of 9K’/11.

The electric field in a region is radially outward with magnitude E = ar. If a = 100 V/m^2 and R = 0.30 m then the value of charge contained in a sphere of radius R centred at the origin is W × 10^−10 C. Find W.
