Consider a huge charge reservoir at potential V=200V=200 volts. A spherical capacitor C1=40nFC_{1}=40 n F is brought in contact with the charge reservoir and then removed. Afterwards, another spherical capacitor C2=30nFC_{2}=30 n F is brought in contact with C1C_{1} and removed. This process is repeated many times. Assume that potential of reservoir does not change during this exercise. Then the charge in (μC)(\mu C) on C2C_{2} after a very long time is :
