Physics: 5 problems, Electric Forces and Electric Fields

See attached file. 1. An electron is released a short distance above Earth's surface. A second electron directly below it exerts an electrostatic force on the first electron just great enough to cancel the gravitational force on it. How far below the first electron is the second? 2. Three charges are arranged as shown in

Like charges on two identical balls

Two identical metal balls bear the same amount and sign of electric charge because they have been touched together. The mass of each ball is 2.00 grams. One ball is mounted on an insulating post. The other ball is suspended from a bifilar silk thread suspension system so that it can move on a 0.500 meter radius. When the two

Working with electric forces, field and potentials.

Two positive charges, charge q0 are fixed on the x axis at positions +a and -a. a) What is the Electric Field anywhere in the (x,y) plane, at position (x,y)? Be sure your answer clearly denotes the vector nature of the electric field. b) What is the electric potential at position (x,y)? c) A third charge, q3 , (mass m3
