Question 32
H

A spring hangs from a clamp. A load is hung from the bottom of the spring.

The spring stretches and then stays still.

Which statement explains why the spring stretches?

[1]
A

Only the load pulls on the spring, and one force is enough to stretch it

B

The load pulls down and the clamp pulls up, so two forces act on the spring

C

The weight of the spring pulls up on the clamp, so the spring is stretched

D

The resultant force on the spring is downwards, so the spring is stretched
