Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 13.1 mm. In this configuration, q1 exerts a repulsive force of 2.62 μN on q2. Particle q2 is then moved to x2 = 19.0 mm. What is the force (magnitude and direction) that q2 exerts on q1 at this new location? (Give the magnitude in μN.) magnitude μN direction
