In each situation of column-I, some charge distributions are given with all details explained. In column -II The electrostatic potential energy and its nature is given situation in column -II. Match the proper entries from column-2 to column-1 using the codes given below the columns, Column-I

Answer

(A) p, s (B) q, s (C) q, s (D) s

Explanation

Electrostatic potential energy=self energy+ interaction energy+interaction energy
(A) Self energy of uniformly charges thin shell
`(KQ^(2))/(2a)` (radius a)
(B) Self energy`=(KQ^(2))/(2xx(5a)/2)` &
Interaction energy`=(KQ^(2))/((5a)/2)`
(C) Self energy of solid sphere of radius `'a'=(3KQ^(2))/(5a)`
