Question:
1. An electron and a proton have charges of an equal magnitude but opposite sign of 1.60 10-19 C. If the electron and proton in a hydrogen atom are separated by a distance of 8.00 10-11 m, what are the magnitude and direction of the electrostatic force exerted on the electron by the proton?
magnitude ________ N
direction--> attractive/repulsive??

2. A test charge of +8.00 10-6 C experiences a downward electrostatic force of 11 N when placed at a certain point in space. What are the magnitude and direction of the electric field at this point?
magnitude _______ N
direction up/down??
