30 A plane loop is shaped in the form as shown in figure with radii a 20 cm and b 10 cm and is placed in a uniform time varying magnetic field B B sin oot where B 10 mT and 100 rad s The amplitude of the current induced in the loop is A if its resistance per unit length is equal to 50 x 10 m The inductance of the loop is negligible X X X XXX X X XB
