Question

A ring of radius 20 cm has a total resistance of 0.04Ω. A uniform magnetic field varying with time t (in sec) as B = 0.4t Tesla is perpendicular to the plane of the ring : (1)The induced current in the ring is 2(pie)/5 A (2)The ring will be in tension. (3)The ring will be in compression. (4)The magnetic field due to ring at centre of ring will be in a direction opposite to the applied magnetic field.

Answer 1

Answer:

Axial electric field due to a circular loop of charge : ( charged ring). Let us consider a uniformly charged ring of radius ' a' having a linear charge density ' 'λ. The total charge.
