Question

Column-I shows some parameters after completion of event and Column-II shows tha arrangements to which these parameters belong.

Column I	Column II
(A) Work done by external agent is negative	(P) Dielectric is being removed slowly from a charged capacitor
(B) Electric field between plates increases	(Q) Dielectric being introduced slowly while battery is connected
(C) Energy of capacitor decreases	(R) Dielectric is being introduced slowly in a charged capacitor
(D) Force between plates remains constant	(S) Plates of capacitor are being slowly moved closer
	(T) Plates of capacitor are being moved slowly in a charged capacitor

(A) Motion is along force then work done is positive

(B) P-iniitial $\frac{E _{0}}{K}$ , final $E_{0}$ S-initial $\frac{V _{0}}{d}$ decreases so E increase

(C) Charge remain same capacitance increases $\frac{Q ^{2}}{2 C}$

(D) $F = \frac{Q}{2 A ϵ _{0}} Q$

where battery is not connected
