Objects A and B are both positively charged. Both have a mass of 550 g , but A has twice the charge of B. When A and B are placed 60 cm apart, B experiences an electric force of 0.39 N .
a. How large is the force on A? N
b. What are the charges on qA and qB?
c. If the objects are released, what is the initial acceleration of A? (m/s^2)
