The plot below shows the electric field as a function of x. The electric potential is zero at x = 0. What is the potential at x = 5 mm? Ex (V/m) A) -5.0 V 2000 B) - 1.0 V C) OV 1000 D) 1.0 V 4 x (mm) E) 5.0 V 2 3 4 5 -1000 -2000Two carbon nuclei are red directly at one another from far away with the same initial velocity. Each nucleus contains 12 protons and 12 neutrons (a neutron has the same mass as a proton but no charge). The radius of a carbon nucleus is 2.7 X 10-15 m. What is the minimum initial velocity needed so that the carbon nuclei make contact at their surfaces? A) 0.88 X 107 m/s B) 1.2 X 107 m/s C) 1.8 X 107 m/s D) 2.0 X 107 m/s E) 2.5 X 107 m/s
