The electric field is a vector quantity.The  direction of the electric field is the same as the direction of the force F on a charge  +q  ,Positive Charge +q  is moving perpendicular to electric field i.e direction of velocity of charge +q is also perpendicular to electric force i.e the force is in the same direction as the field . The electric field from a positive charge points away from the charge.  If the electric field at a particular point is known, the force a charge q experiences when it is placed at that point is given by F = qE .
