We wish to calculate the position of q2 for which the force F12 will have been divided by a 2 with a > O. a) Will q2 move toward or away from 11? Explain your answer b) We call x1 (x1 > 0) the displacement of the particle q2 with respect to its initial position. Knowing that when the particle q2 moved from x1, F12 was divided by a 2. Express the new position of the particle :12, noted x, as a function of d and x1. Justify your choice c) Knowing that when the particle :12 moved from x1, F12 was divided by a 2:; express x1 as a function of d and a. There should be two solutions of which one can be ignored because of the condition imposed on x1
