Match the column-I with column-II.

Match the column-I with column-II. Match the column-I with column-II.

Options

  1. A(A−(p,s)\mathrm{A}-(\mathrm{p}, \mathrm{s}); B−(t)\mathrm{B}-(\mathrm{t}); C−(p,q)\mathrm{C}-(\mathrm{p}, \mathrm{q}); D−(r)\mathrm{D}-(\mathrm{r}))
  2. BA-(s, t); B-(q); C-(s, q); D-(q)
  3. CA−(p,q);B−(q);C−(p,q);D−(p)A-(p, q) ; B-(q) ; C-(p, q) ; D-(p)
  4. DA-(p, t); B-(r); C-(p, q); D-(s)

Correct answer

C. A−(p,q);B−(q);C−(p,q);D−(p)A-(p, q) ; B-(q) ; C-(p, q) ; D-(p)

Step-by-step solution

(P) V=C1V1+C2V2C1+C2V−V1C1=V2−VC2 Total energy =12C1(V−V1)2+12C2(V1−V)2\begin{aligned} & V=\frac{C_1 V_1+C_2 V_2}{C_1+C_2} \\ & \frac{V-V_1}{C_1}=\frac{V_2-V}{C_2} \\ & \text{ Total energy }=\frac{1}{2} C_1\left(V-V_1\right)^2+\frac{1}{2} C_2\left(V_1-V\right)^2\end{aligned}) (Q) V=C1V1+C2V2C1+C2ΔV=12C1+C2(V1−V2)2V−V1C1=V2−VC2\begin{aligned} & V=\frac{C_1 V_1+C_2 V_2}{C_1+C_2} \\ & \Delta V=\frac{1}{2 C_1+C_2}\left(V_1-V_2\right)^2 \\ & \frac{V-V_1}{C_1}=\frac{V_2-V}{C_2}\end{aligned})
