A) \[5\,\,N\]
B) \[10\,\,N\]
C) \[8\,\,N\]
D) zero
Correct Answer: C
Solution :
The frictional force F is given by \[F={{\mu }_{k}}mg\] Given, \[{{\mu }_{k}}=0.4,\,\,\,\,\,m=2kg,\,\,\,\,\,\,\,g=10m/{{s}^{2}}\] \[\therefore \] \[F=0.4\times 2\times 10\] \[F=8N\]You need to login to perform this action.
