1a. Electrostatics Flashcards
1
Q
What is Electric charge, Q?
A
- It is a property of matter
- can be repulsive or attractive
- Measured in Coulombs, C.
2
Q
True or false:
Triboelectric effect is the name for static electricity
A
True
3
Q
What is Coulomb’s Law?
The equation
A
Force = 1/4πε0 * q1q2/r^2
- where like particles repel and unlike particles attract
4
Q
What is the equation for Electric field strength,E?
A
E = F / q
or
E = V/L
5
Q
What directions do the lines of a positive and negative charge go using electric field lines?
A
- positive, outwards
- negative, inwards
6
Q
What is voltage?
A
It is the potential difference between two points, often from electrostatic potentials.
* units are J/C
