The circuit involves two ideal cells connected to a \( 1 \mu \mathrm{F} \) capacitor via a key \( \mathrm{K} \). Initially the key \( \mathrm{K} \) is in position 1 and the capacitor is charged fully by \( 2 \mathrm{~V} \) cell. The key is then pushed to position 2. Column I gives physical quantities involving the circuit after the key is pushed from position 1. Column II gives corresponding results. Match the statements in Column I with the corresponding values in Column II.
Column I
Column II
(P) The net charge crossing the 4 volt cell in \( \mu \mathrm{C} \) is

(Q) The magnitude of work done by 4 Volt cell in \( \mu \mathrm{J} \) is
(2) 6
(R) The gain in potential energy of capacitor in \( \mu \mathrm{J} \) is
(3) 8
(S) The net heat produced in circuit in \( \mu \mathrm{J} \) is
(4) 16
