A) \[60{}^\circ \]
B) \[90{}^\circ \]
C) \[30{}^\circ \]
D) \[45{}^\circ \]
Correct Answer: B
Solution :
In mean position,\[X=\overline{X+Y}\] Net force \[\overline{X+Y}=\overline{X}.\overline{Y}\] \[[k\,\,x]=\] \[k=\frac{1}{x}=\frac{1}{[L]}=[{{L}^{-1}}]\] Let maximum angular displacement with vertical be \[[k]=[{{L}^{-1}}]\]. Then, \[KE=\frac{1}{2}m{{v}^{2}}=kt\] \[\frac{1}{2}m.2v.\frac{dv}{dt}=k\] \[m\frac{dv}{dt}=\frac{k}{v}\]You need to login to perform this action.
