Two capacitors `A` and `B` are connected in series with a battery as shown in the figure. When the switch `S` is closed and the two capacitors get charged fully, then

Options

A. The potential difference across the plates of A is 4V and across the plates of B is 6V
B. The potential difference across the plates of A is 6V and across the plates of B is 4V
C. The ratio of electric energies stored in A and B is `2:3`
D. The ratio of charges on A and B is 3:2

Answer

B

Explanation

In serues `q_(A)=q_(B)=q=10 xx(2xx3)/5xx10^(-6) =12 mu C`
`V_(A)=q/(C_(V))=6V, V_(B)=q/(C_(B))=4V`
in series `U prop 1/C rArr (U_(A))/(U_(B)) =(C_(B))/(C_(A))=3/2`
