Problem:
1. A man and a woman each with no net charge are separated 5 meters.
     a. What negative charge must be transferred from the woman to the man to cause an attraction force of 200N.
     b. Calculate the mass of the transferred charge.

2, A test charge of +3x10^-6 is placed halfway between a charge of -6 mc and a charge of +4 mc that are 40 cm apart. Find the magnitude

3. An electron is present in an electric field of 10^4 v/m
     a. Find the force on the electron.
     b. Find the acceleration on the electron.
