Coulumbs Law:
and consequence of FE pos and neg |
|
Definition
FE = k (q1q2/r2)
FE - e- force between two charge particles. if pos value repel, neg attract
k- proportionality constant: 9x109 Nm2/C2
q1 & q2 - particles
r- distance |
|
|
Term

|
Term
| Principle of Superposition |
|
Definition
| net e- force on charge (q) due to collection of other charges (Q's) is equal to sum of individ forces of each Q on q |

Definition
| charges creating electric feild |
|
|
Term
| in what direction do electric field vetors point in relation to postive and neg charges |
|
Definition
| towards neg charges and away from pos ones |
|
|
Term
Electric Feild eq.
concequence of E being (+) or (-) |
|
Definition
EbyQ = k(Q/r2)
E: electric field, pos value means Q pos mean vector away, neg value means Q neg means vector towards
r: space between Q and where vector goes to
k: 9x109 Nm2/C2
