4. (5 points) Find the electric field a distance z along the axis of a ring with total charge Q and radius r. 5. (5 points) BONUS F Two identical 100 kg mini-spacecraft are initially at rest, 100 m apart, so that each spacecraft is 50m from their common center of mass. At a time t = 0, thrusters produce a force of 3 rN on each spacecraft. The forces are both perpendicular to the initial line between the two, but the force on spacecraft 1 is to the right and that on spacecraft 2 is to the left. Consider a system composed of the two spacecraft. CM + > 100 m a. (2 pts) What is the net torque on the system, relative to an origin at the CM of the system? If those forces remains constant, will the net torque be constant or not? b. (1 pt) c. (2 pts) After 100s, what will be the angular momentum of the system relative to the CM?
