To solve the problem step by step, we will follow these calculations: ### Step 1: Understand the Forces Acting on the Cobalt Piece When the cobalt piece is suspended from the spring, two forces act on it: 1. The weight of the cobalt piece (downward force). 2. The spring force (upward force). ### Step 2: Calculate the Spring Constant (k) ...
