Tripling the weight suspended vertically from a coil spring will result in a change in the displacement of the spring's lower end by what factor?
A)0.33
B)1.0
C)3.0
D)9.0

Question

Quizplus · Accepted Answer

According to Hooke's Law, the displacement of a spring is directly proportional to the force applied. So, if we triple the weight suspended vertically, we increase the force applied by a factor of 3. As a result, the displacement of the spring's lower end will also increase by a factor of 3, since the force and displacement are directly proportional. Therefore, the correct choice is (C) 3.0.
