A) \[\frac{w}{4}\]
B) \[\frac{w}{2}\]
C) \[\frac{3w}{4}\]
D) \[w\]
Correct Answer: C
Solution :
Man is sliding down the telegraphic pole with acceleration\[g/4\]. So, \[mg-F=\frac{mg}{4}\] \[\Rightarrow \] \[F=mg-\frac{mg}{4}\] \[\Rightarrow \] \[F=\frac{3mg}{4}\] \[\Rightarrow \] \[F=\frac{3w}{4}\]You need to login to perform this action.
