A) \[{{\tan }^{-1}}\left( \mu \right)\]
B) \[{{\tan }^{-1}}\left( \frac{\mu }{2} \right)\]
C) \[{{\tan }^{-1}}\left( \frac{\mu }{m} \right)\]
D) \[{{\cos }^{-1}}\left( \mu \right)\]
E) \[{{\tan }^{-1}}\left( \frac{m}{\mu } \right)\]
Correct Answer: A
Solution :
\[\mu =\tan \theta \]where, \[\theta =\]angle of repose\[\Rightarrow \] \[\theta ={{\tan }^{-}}(\mu )\]You need to login to perform this action.
