    Learning Goal: To understand Coulomb's law, electric fields, and the connection between the electric field and the electric force. Coulomb's law gives the electrostatic force F acting between two charges. The magnitude F of the force between two charges q1 and q2 depends on the product of the charges and the square of the distance r between the charges: Part C If the total positive charge is Q = 1.62x10-6 C, what is the magnitude of the electric field caused by this charge at...
