When a 'j' shaped conducting rod is rotating in its own plane with constant angular velocity `omega` about one of its ends P in a uniform magnetic field `rarr B` ( directed normally into the plane of paper ) the magnitude of emf induced across it will be

Options

A. `B omega sqrt(L^(2)+l^(2))`
B. `(1)/(2) B omegal L^(2)`
C. `(1)/(2) B omega (L^(2)+l^(2))`
D. `(1)/(2) B omegal^(2)`

Answer

C
