a) The charges shall be ununiformly distributed on the two cylinders because of the presence of similar charges on both cylinders. In the inner cylinder the charge density will be higher in the axial region while on the outer cylinder the charge density will be higer in the outer region. This is because of the repulsion force bteween the similar charges present.
b) Anequal amount of charge will be induced in the dielectric medium between the two cylinders. Thus the two cylinders induce similar charges on the insulator and the amount of charge induced in the insulating material will be 4Q (3Q +Q). Also it will have higher charge density in the inner surface because of the reduced surface area in the inner surface and comparativery less charge density in the in the outer volume of insulator.
c) The electric field will be zero at every point on the axis because of the symmetry of the arrangement. It goes on increasing in either directions.
