A) \[\mu ({{m}_{1}}-{{m}_{2}})g\]
B) \[\mu ({{m}_{2}}-{{m}_{1}})g\]
C) \[\mu {{m}_{1}}g\]
D) \[\mu ({{m}_{1}}+{{m}_{2}})g\]
Correct Answer: C
Solution :
For motion,\[F\ge \]force of friction\[(f)\] But \[f=\mu N=\mu ({{m}_{1}}+{{m}_{2}})g\] \[\therefore \] \[F\ge \mu ({{m}_{1}}+{{m}_{2}})=g\]You need to login to perform this action.
