The correct answer is:
$300 \mathrm{~J}$
Work done $=$ Area under the curve
$\Rightarrow \mathrm{W}=\frac{1}{2} \times(4-2) \times(400-100)=\frac{1}{2}(2) \times 300$
$\mathrm{W}=300 \mathrm{~J}$
$\Rightarrow \mathrm{W}=\frac{1}{2} \times(4-2) \times(400-100)=\frac{1}{2}(2) \times 300$
$\mathrm{W}=300 \mathrm{~J}$
