A) \[0{}^\circ \]
B) \[30{}^\circ \]
C) \[60{}^\circ \]
D) \[90{}^\circ \]
Correct Answer: B
Solution :
(b) \[30{}^\circ \] \[F=IlB\,\sin \theta \] Or \[\sin \theta =\frac{F}{IlB}=\frac{0.4}{1\times \frac{20}{100}\times 4}=\frac{1}{2}\] \[\Rightarrow \theta =30{}^\circ \]You need to login to perform this action.
