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:

A

`5w//4`

B

`15w//4`

C

`15w//16`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
A
From geometry `:`
`cos theta =(3)/(5)`
`sin theta=(4)/(5)`
As sphere is at equilibrium ,
`T sin theta =w`
`T=(5w)/(4)`.
