A) \[B\,\,{{a}^{2}}\omega \,\,\sin \,\,\omega t\]
B) \[B\,\,{{a}^{2}}\omega \,\,\cos \,\,\omega t\]
C) \[5\,\,\sqrt{2}\,\,B\,\,{{a}^{2}}\]
D) \[10\,B\,\,{{a}^{2}}\omega \,\,\sin \,\,\omega t\]
Correct Answer: D
Solution :
[d] \[\phi =n\,\,BA\,\,\cos \theta =10\,B\,\,{{a}^{2}}\cos \,\omega t\] \[e=-\frac{d\phi }{dt}=-\frac{d}{dt}\left( 10\,B{{a}^{2}}\cos \,\omega t \right)=10\,B\,{{a}^{2}}\sin \,\omega t(\omega ).\]You need to login to perform this action.
