In previous question, if a horizontal force `F=mumg//2` act on the block and the block remains stationary, then tension in string is.

zero

`(3mumg)/(2)`

`(mumg)/(2)`

none of thses

Text Solution

Verified by Experts

The correct Answer is:

`f_(s)gtF` (Since block is stationary)
`f=F` Hence `t=0` .
