The voltage required to balance an oil drop carrying 10 electrons between the plates of a capacitor which are 10mm10 \mathrm{mm} apart, is (Given mass of the oil drop= 3⋅2×10−15kg,e=1.6×10−19C)\left.\mathbf{3} \cdot \mathbf{2} \times \mathbf{1 0}^{-\mathbf{1 5}} \mathbf{k g}, \boldsymbol{e}=\mathbf{1 . 6} \times \mathbf{1 0}^{-\mathbf{1 9}} \mathbf{C}\right)
Q2PhysicsUnit 11: Electrostatics
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 :
