A force of 1200 N compresses a spring from its natural length of 18 cm to a length of 16 cm. How much work is done in compressing it from 16 cm to 14 cm?

$\begin{array}{1 1}3600N.cm\\3000N.cm\\3500N.cm\\2500N.cm\end{array} $

Can you answer this question?

Answer : 3600N.cm
We must work out the spring constant first (we will work in cm)
So $1200 =k(2)$
So $k=600N/cm$
So in this case,
Now the work done is given by :
Work =$\int_2^4 600xdx$
