A spring has natural length $23$ cm $.$ Compare the work $($in J$)W_1$ done in stretching the spring from $23$ cm to $33$ cm with the work $($in J$)W_2$ done in stretching it from $33$ cm to $43$ cm $.($Use $k$ for the spring constant.$)$

$w_1=$

$$ J

$w_2=$

$$ J

How are $W_2$ and $W_1$ related?
