How are two-force members and three-force members similar? 1. They both show how the magnitude of forces can be transmitted through an object.2. They both keep all the forces in parallel lines to each other. 3. They both are constrained by the EOE. 4. They both decrease magnitude as the angle to the force increases

Two charged particles, q1 and q2, are located on the x-axis, with q1 at the origin and q2 initially at x1 = 12.2 mm. in this configuration, q1 exerts a repulsive force of 2.62 µn on q2. particle q2 is then moved to x2 = 18.0 mm. what is the force (magnitude and direction) that q2 exerts on q1 at this new location? (give the magnitude in µn.)
