A positive charge of 78 nano-coulombs is 13 cm from a charge if 98 nano-coulombs. The force on one of the charges due to the other charge is ____ (or blank) newtons. Round your answer to 5 decimal places

A simple electroscope to measure electrical charges is made up of two cork spheres covered with metal sheets, each sphere weighs 1.25x10-4 kg and hangs from a 12 cm long thread, when equal electrical charges are added to the spheres, the force of electrical repulsion moves them away and the angle between the wires indicates the magnitude of the electric charge, if the equilibrium angle between the wires is 500, what is the magnitude of the electric charge?

The figure below shows four small spheres, each with a positive charge, at the corners of a square. The length of each side of the square is a. The sphere at top-right has a charge of q; the one at lower-left has a charge of 6.0q; the other two each have a charge of 5.5g. (Assume that the +x-axis is to the right and the +y-axis is up along the page.) a 5.5g a a 6.0g 5.5q a (a) What is the magnitude of the force on the sphere with charge q? Express your answer in terms of k, q, and a in symbolic form. F = (b) What is the direction of the force on the sphere with charge q? (Enter your answer in degrees counterclockwise from the +x-axis.) counterclockwise from the +x-axis

Two objects charged with an equal amount of charge interact with each other with a force of 3.68 Newton when separated by a distance of 13.3 cm. Determine the magnitude of the charge on each object. Answer: x10-6 C Enter only the coefficient of the scientific notation. For example, you'd enter just just 1.27 if you get 1.27x10-⁹.
