A spring of weight W and force constant ...

A spring of weight `W` and force constant `k` is suspended is a horizontal position by tw3o ligth strings attached to its two ends. Each string makes an angle `theta` with the vertical. The extension of the spring is.

A

`(W//4k)tan theta`

B

`(W//2k)tan theta`

C

`(W//4k)sin theta`

D

`0`

Text Solution

Verified by Experts

The correct Answer is:
B
A spring ……………..
Let `T` = tension in each string.
`2Tcos theta = W` and `T sin theta = kx, x` = extension of spring
or `((W)/(2cos theta))sin theta = kx or x = (W tan theta)/(2k)`
