Under the influence of the Coulomb field of charge +Q, a
charge –q is moving around it in an elliptical orbit. Find out
the correct statement(s)-

1The angular momentum of the charge –q is constant
2The linear momentum of the charge –q is constant
3The angular velocity of the charge –q is constant
4The linear speed of the charge –q is constant

Three concentric metallic spherical shells of radii R, 2R, 3R,
are given charges 1, 2, 3, Q Q Q respectively. It is found that
the surface charge densities on the outer surfaces of the shells
are equal. Then, the ratio of the charges given to the shells,
Q1 : Q2 : Q3 , is-

11 : 2 : 3
21 : 3 : 5
31 : 4 : 9
41 : 8 : 18
