Electric Field

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.
