The magnets of two suspended coil galvanometer are of the same strength so that they produce identical uniform magnetic fields in the region of the coils. The coil of the first one is in the shape of a square of side a and that of the second one is circular of radius (a)/(sqrtpi) . When the same current is passed throught the coils, the ratio of the torque experienced by the first coil to that rxperienced by the second one is

2A current is flowing through a circular coil of radius 10 cm, made of insulated wire and having 100 turns. If the circular plane of the conductor is kept at right angles to the direction of a magnetic field of 0.2Wb.m^(-2) , determine the force acting on the coil.
