If it takes 4.0 N to stretch a spring 6.0 cm and if the spring is then cut in half,what force does it take to stretch one of the halves 3.0 cm?
A)2.0 N
B)4.0 N
C)8.0 N
D)16 N

Question

Quizplus · Accepted Answer

The force required to stretch a spring is directly proportional to the distance it is stretched (Hooke's law). Therefore, if the force required to stretch a spring 6.0 cm is 4.0 N, then the force required to stretch one of the halves 3.0 cm would be half that amount or 2.0 N.

Choice C) 8.0 N and D) 16 N are both incorrect because cutting the spring in half will result in half the force required to stretch it, not twice the force.

Therefore, the correct answer is B) 4.0 N.
