If a charged object is placed in an electric field it will experience a force.

Coloumbs Law

This states that the force of attraction or repulsion between two point charges is equal to k (constant in formula book) multiplied by (charge 1 x charge 2) divided by the radius^{2}. A point charge has a radial field. Uniform field is produced by two parallel plates. From POSITIVE to NEGATIVE.

Electric Field Strength (E): the force that a charged particle will feel i.e. how tightly packed the field lines are.

Charge (Q): Charge on a particle in coloumbs.

**F = EQ E = F/Q ** UNITS: NC^{-1}

Using **F = ma**, we can say F= F and that **a = EQ/m**
