Two point charges, separated by 1.5 cm, have charge values of 2.0 and -4.0 µC, respectively. What is the magnitude of the electric force between them?
Can electric field lines intersect in free space?
A 5.0-C charge is 10 m from a small test charge. What is the magnitude of the force experienced by a 1.0 nC charge placed at the location of the test charge?

A 5.0-C charge is 10 m from a small test charge. What is the magnitude of the electric field at the location of the test charge?

Two 0.20-g metal spheres are hung from a common point by non-conducting threads which are 30 cm long. Both are given identical charges, and the electrostatic repulsion forces them apart until the angle between the threads is 200. How much charge was placed on each sphere?
