Electric Fields Flashcards
1
Q
Total Charge of System
A
Is Conserved
2
Q
Direction of charges
A
Positive points away, negative points towards
3
Q
Between charged plates
A
Uniform Electric Fields exist
4
Q
Equation for electric field
A
E = kq/r^2
5
Q
Equation for electric force
A
FE = qE = kq1q2/r^2
6
Q
How to find the magnitude and direction of electric fields
A
Use vector addition of E kq/r^2
7
Q
forces on microscopic things
A
Protons and Electrons: Same force, but due to F=ma, a is higher for electrons since m is lower
