Discussion Q1 to Q24

Two large , parallel conducting plates X and Y , kept close to each other , are given Q_(1) and Q_(2) (Q_(1) gt Q_(2)) . The four surfaces of the plates are A,B,C and D , as shown (i) The charge on A is (1)/(2) (Q_(1) + Q_(2)) (ii) The charge on B is (1)/(2) (Q_(1) - Q_(2)) (iii) The charge on C is (1)/(2) (Q_(2) - Q_(1)) (iv) The charge on D is (1)/(2) (Q_(1) + Q_(2))

A charge q_(1) is placed at the centre of a spherical conducting shell of radius "R" .Conducting shell has a total charge q_(2) .Electrostatic potential energy of the system is (A) (q_(1)^(2)+2q_(1)q_(2))/(8 pi varepsilon_(0)R) (B) (q_(2)^(2)+2q_(1)q_(2))/(8 pi varepsilon_(0)R) (C) (q_(1)^(2)+q_(1)q_(2))/(8 pi varepsilon_(0)R) (D) (q_(2)^(2)+q_(1)q_(2))/(8 pi varepsilon_(0)R)
