ElectroMagnetic InductionHard

Question

A semicircle loop PQ of radius ′R′ is moved with velocity ′v′ in transverse magnetic field as shown in figure. The value of induced emf. across the ends PQ of the loop is
                                                

Options

A.Bv (πr), end ′P′ at high potential
B.2 BRv, end P at high potential
C.2 BRv, end Q at high potential
D. v, end P at high potential

Solution

e = B (2R) v = 2Brv
