A) \[\frac{v}{g\mu }\]
B) \[\frac{g\mu }{v}\]
C) \[\frac{g}{v}\]
D) \[\frac{v}{g}\]
Correct Answer: A
Solution :
Block B will come to rest, if force applied to it will vanish due to frictional force acting between block B and surface, i,e. force applied = frictional force i.e., \[\mu mg=ma\] \[or\mu mg=m\left( \frac{v}{t} \right)\] \[ort=\frac{v}{\mu g}\]You need to login to perform this action.
