Electric Force and Coulomb's Law between Two Point Charges

Objects A and B are both positively charged. Both have a mass of 500 g, but A has twice the charge of B. When A and B are placed 50.0 cm apart, B experiences an electric force of 0.810 N.

1) How large is the force on A?
2) What are the charges q_A and q_B?
3) If the objects are released, what is the initial acceleration of A?

Solution Summary

The solution is an application of Coulomb's law to calculate the electric force on the sphere. All workings are shown with brief explanations.
