A,B and C are three concentric metallic shells . Shell A is the innermost and shell C is the outermost. A is given some charge (i) The inner surfaces of Band C will have the same charge (ii) The inner surfaces of B and C will have the same charge density (iii) The outer surfaces of A,B and C will have the same charge (iv) The outer surfaces of A,B and C will have the same charge density
