38. A puck of mass m, is tied QIC to a string and allowed Sto revolve in a circle of m1 R radius R on a friction- table less, horizontal The other end of the string passes through a small hole in the cen- m2 ter of the table, and an object of mass m2 is tied to it (Fig. P6.38) The suspended object remains in equilibrium while the puck on the tabletop revolves. Find symbolic expressions for (a) the tension in the string, (b) the radial force acting on the puck, and (c) the speed of the puck. (d) Qualitatively describe what will hap- pen in the motion of the puck if the value of m, is increased by placing a small additional load on the puck. (e) Qualita tively describe what will happen in the motion of the puck if the value of m, is instead decreased by removing a part of the hanging load Figure P6.38
