A) \[\frac{B\ell v}{R}\]clockwise
B) \[\frac{B\ell v}{R}\]anticlockwise
C) \[\frac{2B\ell v}{r}\]anticlockwise
D) 0
Correct Answer: D
Solution :
Induced \[emf=e=-\frac{d\phi }{dt},\]where \[\phi =\vec{B}.\vec{A}\] As both \[\vec{B}\]and \[\vec{A}\]are constant so \[\phi \]is constant, hence induced emf in the loop is zero. Hence, the correction option is [d].You need to login to perform this action.
