[ 2MID ] Physics - Coulomb's Law

Charles-Augustin De Coulomb

What is the name of the French Engineer who measured the magnitude of the electric force between charges at rest?

8.99x10^9 Nm^2/C^2

In the formula F = k q1q2/r2, what is the value of K?

Net Electric Charge

What is the total charge found in an electrical system?

-1.602x10^-19 C

What is the net charge of a single electron?

+1.602x10^-19 C

What is the net charge of a single proton?

Coulomb’s Law

What states that the electric force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of distance between the two objects?

Zero

What is the net charge of the an atom with 3 protons and 3 electrons?

Neutral Atom

What kind of atom is made of equal number of protons and electrons?

Ion

What do you call an atom with a charge?

Coulombs

What is the unit used to express charges of objects?

Electron

This is a fundamental particle which is part of protons and neutron

Proton

This fundamental particle has 2 up quarks and 1 down quark

Neutron

This fundamental particle has 2 down quarks and 1 up quark

Neutrino

• (A little neutron) Zero charge nearly zero mass

• Moves at a speed of light and pass through almost anything

Gravity

invisible force that pulls individual or objects towards the center of the earth.

Weak Nuclear

force that happen to atom undergo radioactive decay.

Strong Nuclear

forces that holds protons and neutrons in the nucleus

Electromagnetic

combined electricity and magnetism.

6.25x10^18 Electrons

What is 1 coulomb equal to?

Electrostatic Force

If this is the case, therefore we can conclude that there is a force acting on both objects causing them to either move away from each other or go together. What is this force?

Torsion Balance

Which experiment is Charles-Augustin most famous for?

x10^-6

The conversion for Micro (µ)

x10^-9

The conversion for Nano (n)

x10^-12

The conversion for Pico (P)

Principle of Superposition

This principle states that when a number of charges are interacting, the net electrostatic force a given charge is the vector sum of the forces exerted on it due to all other charges. The force between two charges is not affected by the presence of other charges.
