Text Solution

Verified by Experts

The correct Answer is:
B

`dF=(dq)(lambda/(2pi in_(0)R))=((qdtheta)/pi)(lambda/(2pi in_(0)R))`
`F_("net")=underset(0)overset(pi//2)(int)2dF cos theta=(qlambda)/(pi^(2) in_(0)R)`
`rArr underset(0)overset(pi//2)(int) cos theta d theta=(qlambda)/(pi^(2) in_(0)R)`

In Fig. there is a frame consisting of two square loops having resistors and inductors as shown. This frame is placed in a uniform but time-varying magnetic field in such a way that one of the loops is placed in crossed magentic field and the other is placed in dot magnetic field. Both magnetic fields are perpendicular to the planes of the loops. If the magnetic field is given by B = (20 + 10 t) Wb m^(-2) in both regions [l = 20 cm, b = 10 cm , and R = 10 Omega , L = 10 H ), The direction in induced current in the bigger loop will be
