Question
Two wires are stretched through same distance. The force constant ofsecond wire is half as that of the first wire. The ratio of work done to stretch first wire and second wire will be
2 : 1
1 : 2
3 : 1
1 : 3
Solution
A.
2 : 1
As W =
If both wires are stretched through same distance, then
W ∝ k
=
=
= 2 : 1
