A) Zero
B) \[{{30}^{o}}\]
C) \[{{45}^{o}}\]
D) \[{{60}^{o}}\]
Correct Answer: C
Solution :
\[\tan \theta =\frac{{{v}^{2}}/r}{g}=\frac{{{v}^{2}}}{rg}\] \ \[\theta ={{\tan }^{-1}}\left( \frac{{{v}^{2}}}{rg} \right)\]\[={{\tan }^{-1}}\left( \frac{10\times 10}{10\times 10} \right)\] \ \[\theta ={{\tan }^{-1}}(1)=45{}^\circ \]You need to login to perform this action.
