1.	When the load on a wire is slowly increased from `3kgwt` to `5 kg wt`, the elongation increases from `0.61` to `1.02 mm`. The work done during the extension of wire isA. `0.16J`B. `0.016J`C. `1.6J`D. `16J`
Answer» Correct Answer - B Work done `=(1)/(2)` stretching force `xx` extension. Net work done in increasing the length from `0.164mm` to `1.02mm` is `W-W_1=(1)/(2)xx5xx9.8xx1.02xx10^-3-(1)/(2)xx3xx9.8xx10^-3` `=0.016J` So the correct choice is (b).
