Explanation 1) Concept The problem involves the concept of conservation of energy. According to this concept the sum of the kinetic energy and potential energy of a system is constant. 2) Formula Kinetic energy of a particle, K = 1 2 m v 2 Where m- mass of the particle and v - speed of the particle 3) Given Speed of the positron, v = 1.0 x 10 7 m/s Graph: V versus x The scale of the vertical axis is set by Vs = 500.0 V

Rank the six combinations of electric charges on the basis of the electric force acting on 91. Define forces pointing to the right as positive and forces pointing to the left as negative. Rank in increasing order by placing the most negative on the left and the most positive on the right. To rank items as equivalent, overlap them. ▸ View Available Hint(s) [most negative 91 = +1nC 92 = +1nC 91 = -1nC 93 = +1nC 92- +1nC 93 = +1nC -1nC 92- -1nC 93- -1nC 91= +1nC 92 = +1nC 93=-1nC 91 +1nC 92=-1nC 93=-1nC 91 = +1nC 2 = −1nC 93 = +1nC The correct ranking cannot be determined.
