A) No work is done in case of both the springs
B) Equal work is done in case of both the springs
C) More work is done in case of second spring
D) More work is done in case of first spring
Correct Answer: C
Solution :
\[W=\frac{{{F}^{2}}}{2k}\] If both springs are stretched by same force then\[W\propto \frac{1}{k}\] As \[{{k}_{1}}>{{k}_{2}}\] therefore \[{{W}_{1}}<{{W}_{2}}\] i.e. more work is done in case of second spring.
