Two identical wires of iron and copper with their Young's modulus in the ratio 3 : 1 are suspended at same level. They are to be loaded so as to have same extension and hence level. Ratio of the weight is :

Answer»

`1:3`
`2:1`
`3:1`
`4:1`

Solution :Y `PROP` WEIGHT applied
`THEREFORE(Y_(1))/(Y_(2))=(W_(1))/(W_(2))rArr(W_(1))/(W_(2))=3/1`
So the CORRECT choice is (c).
