    127
    Three concentric metallic spherical shells of radii R,3RR, 3R and 9R9R are given charges Q1,Q2Q_1, Q_2 and Q3Q_3, respectively. It is found that surface charge densities on the outer surfaces of the shells are equal. Then the ratio of charges given to shells Q1:Q2:Q3Q_1 : Q_2 : Q_3, is (Neglect the induction effects)
