An electric field is represented by the force on which particle? a neutron a dipole a negative test charge a positive test charge

The correct option is a positive test charge

Electric field can be defined as the electric force per unit charge. The direction of the field is taken to be the direction of the force it would exert on a positive test charge. Because of their force fields, charged particles can exert force on each other without actually touching. Electric fields are generally represented by arrows.
