A) \[2W\]
B) \[W\]
C) \[\frac{W}{\sqrt{2}}\]
D) \[\frac{W}{\sqrt{3}}\]
E) \[\sqrt{3}W\]
Correct Answer: E
Solution :
\[W=mB\text{ }cos\theta =mB\text{ }cos\text{ }{{60}^{o}}\] \[=mB\times \frac{1}{2}\] \[\tau =mB\sin \theta \] \[=mB\sin {{60}^{o}}\] \[=\sqrt{3}W\]You need to login to perform this action.
