1

What is Coulomb's Law?

The force of static charges is proportional to the product of the charges and inversely proportional to the square of the distance between them

2

What kind of law is Coulomb's Law?

An inverse square law (like Newton's Gravitational Law)

3

What is the equation for Coulomb's Law?

Fe=kq1q2/r^2
k=9x10^9
Units= N*m^2/C^2

4

What is charge (q) measured in?

Coulombs (C)

5

What are the types of static charges?

Attraction (-)
Repulsion (+)

6

When is electrostatic force neutralized?

When gravity is present

7

Is electrostatic force conservative?

Yes, W=EqΔr

8

What is Electric Potential?

A measure of the magnitude of electrical potential energy per unit charge at a particular location in the field

9

What is Potential Difference?

The work done per unit charge, in moving for equipontential surface A to equipontential surface B

10

What is potential difference also known as?

Voltage
Units: Volts(V)

11

What is an equipontential surface?

Set of all positions on a circle of radius (r) that experience the same amount of electric potential

12

What is the difference between electric potential and electric potential energy?

Electric potential is a measurement of potential energy; electric potential energy is stored energy in an electric charge
