Two wires of the same material and lengt...

Two wires of the same material and length are stretched by the same force. Their masses are in the ratio `3:2`. Their elongations are in the ratio

`3:2`

`9:4`

`2:3`

`4:9`

Text Solution

Verified by Experts

The correct Answer is:

`Y=(Fl)/(a/_\l)` or `/_\lprop1/a`
Again `m=alrho` or `mpropa`
`:./_\lprop1/m`
`(/_\l_(1))/(/_\l_(2)=(m_(2))/(m_(1)))=2/3`
