A sparrow flying in air sits on a stretched telegraph wire If weight of the sparrow is `W` which of the following is true about the tension `T` produced in the wire ?

A

`T =W`

B

`TltW`

C

`T =0`

D

`TgtW`

Text Solution

Verified by Experts

The correct Answer is:
d
As is clear from
`2 Tcos theta = W,T = (W)/(2 cos theta)`
As `theta ~~ 90^(@) :. T gt W`
