#### Question

The graph between applied force and change in the length of wire within elastic limit is a.......................

- straight line with positive slope.
- straight line with negative slope.
- curve with positive slope.
- curve with negative slope.

#### Solution

(a) straight line with positive slope.

Stress is directly proportional to strain and the elastic limit is

`F/Aprop(DeltaL)/L`

Since, A and L are constants.

**∴ F ∝ ΔL**

Thus, the graph between applied force and change in length is a straight line with

a positive slope.

Is there an error in this question or solution?
