When a block of mass M is suspended by a long wire of length L

Sahay Sir > Question Answers > When a block of mass M is suspended by a long wire of length L
Two wires are made of the same material and have the same volume. The first wire has cross-sectional area A and second wire has cross-sectional area 3A. If the length of first wire increased by Δl on applying force F, how much force is needed to stretch second wire by the same amount?
