Q. Assume the masses described in the preceding problem are 1kg and 100kg in that order. Compare the accelerations while they are interchanged, that is, for the case where the 1 kg mass dangles over the pulley, and then for the case where the 100kg mass dangles over the pulley. What does this indicate about the utmost acceleration of such a system of masses?

Q. An alpha particle (charge = +2.0e) is sent at high speed toward a gold nucleus (charge = +79e). What is the electric force acting on alpha particle while the alpha particle is 1.9 multiplied by 10-14 m from the gold nucleus?
