Find the tension in the string AB loaded...

Find the tension in the string AB loaded with weight W at the middlw, when AB is horizontal:

A

zero

B

W

C

`(W)/(2)`

D

infinity

Text Solution

Verified by Experts

The correct Answer is:
D

In a position as shown
`2Tcostheta=W`
`T=(W)/(2costheta)`
For AB to be horizontal, `theta=90^@`
