Question

rod PQ of length L in rotated about 1end p in a uniform magnetic field which is perpendicular to the plane of rotation of rod. M is the midpoint of rod rotation of rod. M is the midpoint of the induced EMF between mnq if that between P and Q is hundred volt​

Answer 1

Answer:

Explanation:

Solution :

EPQ=12Bω(2l)2=100Vrarrωl2=50V

EPM=12Bω(l)2=25V

EMQ=EPQ−EPM=100−25=75V
