Electric Charges and Forces Principles
Three particles are located on a coordinate system. An electron is located at the origin, a proton is located at (0, 1), and an electron is located at (1, 0). What is the direction of the net electrostatic force on the electron located at the origin?
Point charges W, X, Y, and Z each have the same magnitude charge of 4.46x 10-5 C. Two of the charges are positive as shown and two are negative. The corners of the square are 10.0 cm long. Calculate the net force on each of the point charges. Draw vector
Consider an isolated, neutral system consisting of wool fabric and a rubber rod. If the rubber rod is rubbed with wool to become negatively charged, what can be said about the wool fabric?
A negatively charged object is placed near, but not touching, a neutral conductor. As a result, the two objects are attracted to each other. Which of the following is true?
Sparks are often observed (or heard) on a dry day when clothes are removed in the dark. Explain
Three objects carrying charges of -4.0 x 10-6 C, +6.0 x 10-6 C, and +9.0 x 10-6 C, respectively, are placed in a line, equally spaced from left to right by a distance of 0.50 m. Calculate the magnitude and direction of the net force acting on each that r
How many electrons are responsible for a charge of -9.6 C?
A carbon nucleus has 6 protons. What can be said about the electrostatic force between an orbital electron and the carbon nucleus?
Two protons are 1.0 µm apart. What is the electric force between them?
An electron and a proton are separated by 1.50 X 10^-10 m. If they are released, which one will accelerate at a greater rate, and what is the magnitude of that acceleration?
