A) \[g\]
B) \[\frac{\mu F}{m}\]
C) \[g+\frac{\mu F}{m}\]
D) \[g-\frac{\mu F}{m}\]
Correct Answer: D
Solution :
Here, normal contact force \[N=F\] and friction force, \[f=\mu N\] |
So the free body diagram of boy is as shown adjacent in the above figure. |
Now, \[ma=mg-f\] |
\[\Rightarrow \] \[a=g-\frac{\mu F}{m}\] |
