Two identical small charged spheres, each having a mass of 3X10^-2kg, hang at equilbrium. The length of the string is .2m, the angle between each string and the perpendicular is 10 degress. A=.034M A) What is the tension in the string B) Electric force felt by each sphere C) Charge of each sphere D) If the spheres were neg
Find the ratio of the electric force to the gravitational force between two electrons.
Each of two small spheres is charged positively, the combined charge being 5 x 10^-5 C. If each sphere is repelled from the other by a force of one newton, when the spheres are two meters apart, how is the total charge distributed between the two spheres ?
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
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
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
