Protons of mass 1.68 x 10 27 kg, traveling to the right with an initial velocity of 1 x 100 m/s, enter an electric field of 1x10 N/C directed into the plane of the page. The path followed by the protons is now: O the protons move at constant velocity into the plane of the page. O the protons are accelerated out of the plane of the page. the protons continue to move in a straight line to the right at velocity 1 x 10° m/s. O the protons are accelerated to the right. O the protons are accelerated into the plane of the page.
