Two tiny spheres have the same mass and carry charges of the same magnitude. The mass of each sphere is 5.04 10-6 kg. The gravitational force that each sphere exerts on the other is balanced by the electric force. Determine the charge magnitude.
A jogger travels a route that has two parts. The first is a displacement of 2.00 km due south, and the second involves a displacement that points due east.
