In the Milikian oil drop experiment, an atomizer (a sprayer with a fine nozzle) is used to introduce tiny oil droplets between two oppositely charged parallel plates held in a vacuum chamber. Some of the droplets pick up excess electrons. The charge on the plate is adjusted so that the electric force on the excess electrons exactly balances the weight of the droplet, leaving the droplets levitating. The resulting equilibrium allows one to measure the electric charge of a droplet. If the droplets have a diameter of about 0.2mm, and the E-field between the plates is moderately strong 30,000 N/C, estimate how many excess electrons would be needed on the drop so that the electric force could hold the weight of the drop.

In what way or ways would the physical universe be different if protons were negatively charged and electrons were positively charged? 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. Like charges would attract, and opposite charges would repel. Atoms would consist of protons orbiting a nucleus composed of electrons and neutrons. There would be no difference other than the sign on the charged particles.
The classic Millikan oil drop experiment setup is shown below. In this experiment oil drops are suspended in a vertical electric field against the gravitational force to measure their charge. If the mass of a negatively charged drop suspended in an electric field of 1.76 ✕ 10−4 N/C strength is 8.620 ✕ 10−21 g, find the number of excess electrons in the drop.
You plan to shock your sibling with an electrostatic charge. To do this, you need to collect electrons from your carpet by rubbing your feet. Your sibling has +8.2 10-6 C excess charge. (a) What is the minimum amount of electrons you would need to shock your sibling assuming your sibling will be neutral after the shock?(b) What is the minimum mass you will be losing? (kg)
Imagine you have four identical charge q, placed on the corners of a square. If q = 14.77 uC, then the side of the square is s = 13.04 cm, calculate the energy needed to bring these charges from infinity to their current configuration. NOTE: Final answer in THREE decimal places. Then, state the SI unit of the variable being sought off. Add your answer
The three charge configurations are shown in the figure. For the values of q1=3.5uC, q2=-3.5 MC and q3=5 uC. The Forces of the three charges is calculated at q3. (Note:u=micro= 10^-6, If q3 has the mass of 10 grams, what will be the initial acceleration of q3 in m/s^2, due to q1 and q2?
Two small balls with a mass of 2 g each are hanging on two separate strings 0.25 m (25 cm) long attached to a common point. They are given an identical negative charge and spread apart to a distance 3 cm from each other. Determine the charge on each ball by finding the forces in equilibrium and using Coulomb's law. How many electrons are there on each ball? What will happen in an identical situation if the mass of the balls is cut in half? What would happen if the charge on each ball is doubled?
In the video, the students discussed with the professor how objects can become charged through contact interactions at the microscopic level. Which of the following could possibly happen when two neutral objects are rubbed together? There may be more than one possibility. (Select all that apply.) A.Friction between the two objects can destroy electrons in them, allowing both to have a net positive charge after contact B.Rubbing imparts energy to the two objects, allowing them to create excess electrons and thereby allowing both to have a net negative charge after contact. C.There might not be any changes to the chemical bonds between atoms, and the two objects remain neutral after contact. D.Chemical bonds can break in such a way that atoms in the objects can gain or lose electrons. One object can gain electrons overall, with the electrons coming from the other object. The two objects thereby end up with opposite net charges.
In a Millikan Oil-Drop type experiment, oil drops with an excess charge of two electrons are suspended between the two plates. If the mass of the oil drop is one million times the mass of the proton, and the plates are 2.5 cm apart, what is the voltage of the upper plate relative to that of the lower plate? Assume a uniform field between the two plates.
