Abowling ball has a mass of 7.2 kg and a weight of 70.6 n. it moves down the bowling alley at 1 m/s and strikes a pin with a force of 15.0 n. what is the force that the pin exerts on the bowling ball?

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.)
