Solve the all parts of given problem:
Problem: A balloon is rubbed with a wool glove. The two items attract one another with a force of strength 1.5 N when they are 1 cm apart. If they have equal but opposite charges,
Part A: What is the magnitude of the charge?
Part B: How many electrons were transferred?
Please explain clearly with details so that I can follow.
