When a rubber band is strecthed by a distance x, it exerts a restoring force of magnitude F = ax +bx2, where a and b are constants. The work done in stretching are unstretched rubber-band by L is

• aL2 +bL2

C.

Given, F = ax +bx2
We know that work done in stretching the rubber band by L isÂ
|dW|= |Fdx|

Given, F = ax +bx2
We know that work done in stretching the rubber band by L isÂ
