Two plates made of the same material and thickness are joined as shown. One plate is circular and another square in shape. The diameter of circular plate is equal to the side of the square plane. Locate `c.m.`

Two uniform discs made of same material and thickness of redii R and 2 R are joined as shown. Locate c.m.

A square plate and a circular plate made up of same meterial are placed touching each other an a horizontal table. If the side length of square plate is equal to diameter of the circular plate then the centre of mass of the system will be

Between the plates of a parallel plate capacitor of capacity C, two parallel plates, of the same material and area same as the plate of the original capacitor, are placed. If the thickness of these plates is equal to 1/5 th of the distance between the plates of the original capacitor, then the capacity of the new capacitor is

On a square cardboard sheet of area 784 cm^(2) , four congruent circular plates of maximum size are placed such that each circular plate touches the other two plates and each side of the square sheet is tangent to two circular plates. Find the area of the square not covered by the circular plates.
