Problem 1. 10. Reproduce Figure Q22.10 on your paper. Then draw a dot (or dots) on the figure to show the position (or positions) at which the electric potential is zero. Figure Q22.10 II+III Problem 2. 3. An electron moves along the trajectory of Figure Q22.30 from i to f. a. Does the electric potential energy increase, decrease, or stay the same? Explain. b. Is the electron's speed at f greater than, less than, or equal to its speed at i? Explain . Figure Q22.3 Problem 3. Consider the arrangement of three point charges each at the vertex of an equilateral triangle with side length a = 1cm as shown in the figure below: Itinc a + 0.01 m +Inc Suppose each charge weighs 1 gram. If all charges are released at the same time, what is the speed of each particle at infinity
