- Two electrons in an atom are separated by 1.6 × 10-10 m, the typical size of an atom. What is the force between them? Coulomb constant is 9 × 10⁹ Nm²/C². Answer in units of N. The T 06An electron is in a vacuum near Earth's surface and located at y = 0 m on a vertical y axis. At what value of y should a group of 3 electrons be placed such that its electrostatic force on the first electron balances the gravitational force on the first electron?Two charged spheres are separated by a distance R. The charges experience a force F. One of the spheres is then replaced with a new sphere that has twice the charge and is a distance of 0.5R away. What is the new force? Question 1 options: 4F 2F 8F F
- A light, unstressed spring has length d. Two identical particles, each with charge q, are connected to the opposite ends of the spring. The particles are held stationary a distance d apart and then released at the same moment. The system then oscillates on a frictionless, horizontal table. The spring has a bit of internal kinetic friction, so the oscillation is damped. The particles eventually stop vibrating when the distance between them is 3d. Assume the system of the spring and two charged particles is isolated. Find the increase in internal energy that appears in the spring during the oscillations.Situation: Which material that is rubbed with cotton would attract a positively charged human hair. There are 4 candidates, namely: glass, fur, silicon, and acetate. By rubbing the pairs of materials, the signs of the resulting charges were determined. The data is based on the image.

Note: for this question, there may be more than one correct answer! -4.34 x 10-18 J -13.7 eV -27.1 eV -8.19 x 10-8 JIn the picture below, the rod is positively charged. Electrically speaking, water is a "polar molecule"; each water molecule can be imagined as a negative charge (the oxygen end) and a positive charge (the hydrogen end), each of approximate magnitude 2e, separated by an approximate distance of 2 x10-1" m. a) Explain how a charged rod can exert an electric force on water molecules that have zero net charge. Include a picture of a typical water molecule in the stream of water adjacent to the rod, showing its orientation relative to the rod. b) If the charge of the rod is +32 nC and that charge is located approximately 2.0 cm from a water molecule in the stream, what is the maximum possible net electric force that the rod could exert on the molecule?
