Column II gives certain systems undergoing a process. Column I suggests changes in some of the parameters realated to the system. Match the statement in Column I to be appropriate process(es) from column II.

Answer

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

Explanation

(i) Energy of capacitor is less `1//2 cv^(2)` therefore p.
(ii) work is done on the gas hence energy increases therefore q.
(iii) When mass decreases its energy increases.
(iv) when current flows energy of magnetic of magnetic field is generated therefore t.
(B) work is done on the gas
(C) mass is reduced and mass defect is converted into energy.
(D) mass decreases due to mass defect.
