If two springs

S_{1}

and

S_{2}

of force constants

k_{1}

and

k_{2}

, respectively, are stretched by the same force, it is found that more work is done on spring

S_{1}

than one spring

S_{2}

.

Assertion: If stretched by the same amount, work done on $S_{1}$ will be more than that on $S_{2}$ .

Reason: $k_{1} < k_{2}$ .
