Answer:the force is needed to stretch it farther.

Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.

Jimena Jimenez · Answer 2

The rubber band works as a spring, so the force that you need to stretch it would be equal to:

F = X*k where X is the change in the perimeter of the rubber band and k is a constant of the rubber band.

So you need to apply force to stretch it, and when you put it again in the stack of papers, the stack of papers applies a normal force against the rubber band that keeps the rubber band a little bit stretched.
