In Fig. 16-36 a, string 1 has a linear density of 3.00 g/m, and string 2 has a linear density of 5.00 g/m. They are under tension due to the hanging block of mass M = 500 g. Calculate the wave speed on (a) string 1 and (b) string 2 (Hint : When a string loops halfway around a pulley, it pulls on the pulley with a net force that is twice the tension in the string.) Next the block is divided into two blocks (with M 1 +M 2
​ =M) and the apparatus is rearranged as shown in Fig. 16-36b. Find (c) M 1 and (b) M 2 such that the wave speeds in the two strings are equal.
