Listen A uniform electric field has a magnitude of 4.7 x 104 N/C. A charged particle experiences a force of 8.2 N when placed in this electric field. What is the magnitude of the charge on this particle? O 1.74 x 10-4 C 3.12 x 10 4 C 5.73 x 103 C 3.85 x 105 C Question 17 (1 point) Listen D Electric field lines: Point in the same direction as the force that would act on a positive test charge Represent the amount of energy that charges have near other charged objects Point away from negative charges and towards positive charges All of the above are true Question 18 (1 point)
