A) \[>\frac{a}{g}\]
B) \[<\frac{g}{a}\]
C) \[=\frac{a}{g}\]
D) \[>\frac{g}{a}\]
Correct Answer: D
Solution :
[d] Force on M = Mg Reaction force=Ma Force of friction\[=\mu R=\mu .Ma\] Force of friction will balance the weight .So \[\mu Ma\ge Mg\,\,;\] \[\mu \ge \frac{g}{a.}\]You need to login to perform this action.
