A uniform sphere of weight W and radius ...

A uniform sphere of weight `W` and radius 3 `m` is being held by a frictionless wall as shown in the figure. The tention in the string will be:

5 W/4

15 W/4

15 W/16

None of these

Text Solution

Verified by Experts

The correct Answer is:

`W=T sin theta`

`cos theta=3//5rArr theta=53^(@)`
`T=(W)/(sin53^(@))=(5)/(4)W`
