Solve the following problems:
Problem 1: Two point charges have a total charge of 560 µC when placed 1.10m apart. The force each exerts on the other is 22.8N and is repulsive. What is charge on each other?
Problem 2: Compare the electric force holding the electron in orbit (r= 0.53x10^-10m) around the proton nucleus of the hydrogen atom, with the gravitational force between the same electron and proton. What is the ratio of these forces?
Problem 3: A charge of 6.00 mC is placed at each corner of a square .100m on a side. Determine the magnitude and direction of the force on each charge.
