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? The Coulomb constant is 9 × 10^9 N · m^2/C^2 . Answer in units of N.
In bronze, a singly ionized copper atom and a doubly lonized tin atom are separated by a distance R-24.1 nm. Both are positively charged and so should repel, but they
are kept in place by their attraction to an electron in-between the two ions.
As a result of the combination of electrostatic forces between the ions and the electron, the three particles are kept in equilibrium, as shown in the figure below.

Gravity would be a repulsive force instead of an attractive one. Since protons are more massive, the universe would acquire a net negative charge. The value of the Coulomb constant k would change.

There would be no difference other than the sign on the charged particles.arrow_forward

- Because of their net negative charge, bacteria are easily attracted to and adhere to surfaces on which they can proliferate, forming bacterial biofilms, thin films of bacteria coating the surface. Bacterial biofilms are especially problematic on indwelling medical devices (IMDS), which are devices inserted into a patient and include catheters, heart valves, and artificial joints. Contaminated IMDS are the most common source of infection in humans. A number of mitigation methods are in use today, including antibacterial graphene oxide coatings and the use of electric fields and surface charges to repel bacteria.

The small print on the battery in your hand says 1530 mAh. Can you express this amount of electric charge using the usual coulomb units? You are now charging a camera battery. The charger moves 4470 C of electric charge from the negative terminal of the battery to the positive terminal. (In reality the charger moves the negative electrons from the positive terminal to the negative terminal, but this is not important for us right now.) Assuming - incorrectly - that the voltage of the battery remains a constant 3.20 V during the whole charging process, determine the work done by the charger. And now you are charging a capacitor bank for a high-voltage physics experiment. The power supply moves Q = 8990 C of electric charge in the charging process. The supply is set to stop, when the voltage reaches AV = 710 V. How much work did the power supply perform?arrow_forward
