# Motion of a Charged Particle in a Uniform Electric Field

If an object having an electric charge *q *is at a point in space where the electric field is E, the force on the object is given by

F = *qE*

We already have learnt how to determine E for some particular situations. Now let us suppose we know E and we want to find the force on a charged object and the object’s subsequent motion. (We assume no other forces act.)
