Question: An unstrained horizontal spring has a length of 0.28 m and a spring constant of 201 N/m. Two small charged objects are attached to this spring, one at each end. The charges on the objects have equal magnitudes. Because of these charges, the spring stretches by 0.019 m relative to its unstrained length.
Part A: Determine the possible algebraic signs and the magnitude of the charges.
Please show how you obtained the possible algebraic signs and the magnitude of the charges.
