A) \[12\,V\]
B) \[6\,V\]
C) \[\frac{4\,V}{3}\]
D) \[\frac{3\,V}{2}\]
Correct Answer: B
Solution :
As, \[\frac{{{V}_{A}}}{{{V}_{B}}}=\sqrt{\frac{{{r}_{B}}}{{{r}_{A}}}}\] \[\Rightarrow \] \[\frac{3V}{{{V}_{B}}}=\sqrt{\frac{R}{4R}}\] \[\Rightarrow \] \[{{V}_{B}}=6V\]You need to login to perform this action.
