Question

A light spring of unstretched length 14.2 cm is suspended vertically from a fixed point, as shown in the first figure below. A mass of weight 3.8 N is hung from the end of the spring, as shown in the second figure below. The length of the spring is now 16.3 cm. An additional force F then extends the spring so that its length becomes 17.8 cm, as shown in the third figure below. (spring obeys Hooke's law). You are required to find the magnitude of the force F.

Step 1

First, we need to find the spring constant (k) using Hooke's law. Hooke's law states that the force exerted by a spring is proportional to its elongation (or compression) from its equilibrium position: F = -kx, where F is the force exerted by the spring, k is the Show more…
