A) \[{{a}^{0}}{{b}^{0}}{{c}^{0}}\]
B) \[{{a}^{-1}}{{b}^{0}}{{c}^{0}}\]
C) \[{{a}^{1}}{{b}^{0}}{{c}^{0}}\]
D) \[{{a}^{-1}}{{b}^{-1}}{{c}^{0}}\]
Correct Answer: B
Solution :
| Here, we look for an equation involving velocity v, acceleration g and length r and coefficient of friction \[{{\mu }_{s}}\]. We arrive at |
| \[{{\mu }_{s}}=\tan \theta =\frac{{{v}^{2}}}{rg}=\frac{{{b}^{2}}{{c}^{-2}}}{b{{c}^{-2}}ab}={{a}^{-1}}{{b}^{0}}{{c}^{0}}\] |
