A metal sphere is hung by a string fixed to a wall. The forces acting on the sphere are shown in fig Which of the following statements are correct?

A

`vec(R)+vec(T)+vec(W)=0`

B

`T^(2)=R^(2)+W^(2)`

C

`T=R+W`

D

`R=W tan theta`

Text Solution

Verified by Experts

The correct Answer is:
A, B, D

`T^(2)=R^(2)+W^(2)`
`Sigmavec(F)_("net")=0`
So, `vec(T)+vec(W)+vec(R)=0`
