Two square plates of side 'a' are arranged as shown in the figure. The minimum separation between plates is 'd' and one of the plate is inclined at small angle `alpha` with plane parallel to another plate. The capacitance of capacitor is (given `alpha` is very small)

For a parallel plate capacitor of capacitance C and plate separation d,

Four metal plates numbered 1,2,3 and 4 are arranged , as shown in figure . The area of each plate is A and the separation between them is d . The capacitance of the arrangement is

A copper plate of thickness b is placed inside a parallel plate capacitor of plate distance d and area A as shown in figure. The capacitance of capacitor is

A copper plate of thickness b is placed inside a parallel plate capacitor of plate distance d and area A as shown in figure. The capacitance of capacitor is

One plate of a parallel plate capacitor is tilted by a small angle about its central line as shown in the Figure. The tilt angle theta is small. Both the plates are square in shape with side length a and separation between their centers is d. Find the capacitance of the capacitor.
