E = Fel/q
- E electric field in N/C
- Fel electric force in N
- q electric charge in C
Example
A charge of 2.0 x 10-6 C is placed at a certain place in an electric field
The electric force on that charge is 1.0 x 10-3 N.
Calculate the magnitude of the electric field at that place.
E = Fel/q
E = (1.0 x 10-3)/2.0 x 10-6 = 5.0 x 102 N/C
In a uniform electric field is the field of the same magnitude and direction at all places.
