A right angled triangle abc, made from a metallic wire, moves at a uniform speed v in its plane as shown in . A uniform magnetic field B exists in the perpendicular direction. Find the emf induced (a) in the loop abc, (b) in the segment bc, (c ) in the segment ac and (d) in the segment ab.

Options

A. zero: `vB(bc),+ve` at `c` , zero, `vB(bc),+ve` at a
B. `vB(bc),+ve` at `c` , zero, `vB(bc),+ve` at a
C. zero, zero `vB(bc),+ve` at `c` , `vB(bc),+ve` at a
D. `vB(bc),+ve` at `c` , `vB(bc),+ve` at `a` , zero, zero

Answer

A

Explanation

`bc` :
`ac` : `e=0`
`ab` :
