Solve the all parts of following problem given below:
Problem: An unstrained horizontal spring has a length of 0.32 m and a spring constant of 300 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 0.026 m relative to its unstrained length.
Part A: Determine the possible algebraic signs?
Part B: Determine the magnitude of the charges?
Please show how you obtained the magnitude of the charges.
