The length of a wire increases by 1% by a load of 2 kg-wt. The linear strain produced in the wire will be

To find the linear strain produced in the wire, we can use the definition of strain.

Linear strain (often denoted by $\epsilon$) is defined as the ratio of the change in length of the body ($\Delta L$) to its original length ($L$):

$\mathrm{Strain}=\frac{\Delta L}{L}$

The problem states that the length of the wire increases by 1%. This means that the change in length is 1% of the original length:

$\Delta L=1\%·L=\frac{1}{100}·L=0.01·L$

Substituting this relationship into the formula for linear strain, we get:

$\mathrm{Strain}=\frac{0.01·L}{L}=0.01$

Thus, the linear strain produced in the wire is 0.01.

The correct option is 0.01.
