A) \[\frac{2{{V}^{2}}}{JS}\]
B) \[\frac{{{V}^{2}}}{4JS}\]
C) \[\frac{{{V}^{2}}}{J}\]
D) \[\frac{{{V}^{2}}S}{2J}\]
Correct Answer: B
Solution :
\[W=JQ\] Þ \[\frac{1}{2}\left( \frac{1}{2}m{{V}^{2}} \right)=J\times mS\Delta \theta \] Þ \[\Delta \theta =\frac{{{V}^{2}}}{4\,JS}\]You need to login to perform this action.
