Seven capacitors each of capacitance $2 μ F$ are to be connected to obtain equivalent capacitance of $(\frac{10}{11}) μ F$ . Which of the following combination is possible?

Options:

Answer:

Solution:

In SHM, V $= A^{2} - x^{2}$ $V = A^{2} - \frac{4 A ^{2}}{9} = \frac{5 A ^{2}}{9}$ $3 V = A^{'2} - \frac{4 A ^{2}}{9}$ Dividing the above two equations give $A^{'} = \frac{7 A}{3}$
