    Figure shows two capacitors \[{{C}_{1}}\] and \[{{C}_{2}}\] connected with 10 V battery and terminal A and B are earthed. The graph shows the variation of potential as one moves from left to right. Then the ratio of \[\frac{{{C}_{1}}}{{{C}_{2}}}\] is -  

    A) \[\frac{5}{2}\]              

    B)   \[\frac{2}{3}\]

    C) \[\frac{2}{5}\]                          

    D) \[\frac{4}{3}\]

    Correct Answer: B

    Solution :

    \[{{V}_{{{C}_{1}}}}=10-4=6V\] \[{{V}_{{{C}_{2}}}}=4-0=4V\] \[\frac{{{V}_{{{C}_{1}}}}}{{{V}_{{{C}_{2}}}}}=\frac{{{C}_{2}}}{{{C}_{1}}}\,\,=\,\,\frac{{{C}_{1}}}{{{C}_{2}}}=\frac{{{V}_{{{C}_{2}}}}}{{{V}_{{{C}_{1}}}}}=\frac{4}{6}=\,\,\frac{2}{3}\]
