If the tension on a wire is removed at once, then

A

will decreases slightly

B

will increases slightly

C

will not change

D

may increase or decrease, depending upon the surrounding conditions

Text Solution

Verified by Experts

The correct Answer is:
B
When the wire is stretched by applying a tension, then the work done in increasing its length increases its potential energy. When the tension is suddenly removed, the interatomic distances are decreased and hence the P.E. is also decreased. This change in P.E. appears as heat in the wire and hence its temperature is slightly increased.
