Aparticle has a charge of +1.7 μc and moves from point a to point b, a distance of 0.18 m. the particle experiences a constant electric force, and its motion is along the line of action of the force. the difference between the particle's electric potential energy at a and b is epea - epeb = +8.3 x 10-4 j. (a) find the magnitude of the electric force that acts on the particle. (b) find the magnitude of the electric field that the particle experiences.
