Question 1013506: A hot air balloon acquires a charge of 6.4x10^-6 C on its surface as it travels through the air. Another hot air balloon acquires a charge of 1.4x10^-4 while flying. How much electrostatic force is between them if the distance between them is .81m apart?

Coulomb's law states that
so that
F = (8.99 x 10^9)(6.4 x 10^-6)(1.4 x 10^-4) / (.81)^2
F = 12.3 N repulsive
