A gang capacitor is formed by interlocking a number of plates as shown in figure. The distance between the consecutive plate is 0.885 cm and the overlapping area of the plates is 5cm^2 . The capacity of the unit is

Thickness of a wooden circular plate is same as the thickness of a metal circular plate but density of metal plate is 8 times density of wooden plate. If moment of inertia of wooden plate is twice the moment of inertia of metal plate about their natural axes, then the ratio of radii of wooden plate to metal plate is

A flat metallic plate and another cap-shaped metallic plate are placed together to form a capacitor as shown in the adjoining figure. Calculate the capacitance of the combination, if plate separation and area of the plates are as shown in the figure (m).

Two plates with diameters 3.5 cm and 2.5 cm are kept one above the other. The larger plate is placed at the bottom. What is the total area of the larger plate in sq.cm that is visible?

Two plates of equal area are placed in contact with each other. The thickness of the plates are 2.0 cm and 3.0 cm respectively. The outer face of first plate is at -25^(@) C and that of second plate is at +25^(@) C . The conductivities of the plates are in the ratio 2:3 . Calculate the temperature of the common surface of the plates.
