Coulomb's Law with Calculus Video Lessons

Concept

# Problem: Two charged pith balls are suspended on very light 10.5 cm strings. Each has a mass of 11.0 g. In equilibrium, the total angle between the strings is 35.0 degrees. Draw a free-body diagram for one of the pith balls and clearly label all forces with magnitude and direction.

###### FREE Expert Solution

The weight is directed vertically downward.

The repulsion due to electric force is directed horizontally.
