A) \[0{}^\circ \]
B) \[\frac{\pi }{3}\]
C) \[\frac{\pi }{6}\]
D) \[\frac{\pi }{4}\]
Correct Answer: D
Solution :
[d] Given; \[speed=10\text{ }m/s;\]radius \[r=10\text{ }m\]Angle made by the wire with the vertical \[\tan \,\theta =\frac{{{v}^{2}}}{rg}=\frac{{{10}^{2}}}{10\times 10}=1\Rightarrow \theta ={{45}^{o}}=\frac{\pi }{4}\]You need to login to perform this action.
