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 electrical energies stored in A and B is 2 : 3
D) The ratio of charges on A and B is 3 : 2
Correct Answer: B
Solution :
In series combination of capacitors, voltage distributes on them, in the reverse ratio of their capacitance i.e. \[\frac{{{V}_{A}}}{{{V}_{B}}}=\frac{3}{2}\] ......(i) Also \[{{V}_{A}}+{{V}_{B}}=\text{ 1}0\] .......(ii) On solving (i) and (ii) \[{{V}_{A}}=\text{ 6}V,{{V}_{B}}=\text{ 4}V\]You need to login to perform this action.
