In figure a, string 1 has a linear mass density of 3 g/m, and string 2 has a linear mass density of 4.5 g/m. They are under tension due to the hanging block of mass M = 500 g as shown in figure (A)

The block is now divided into two blocks (with M1 + M2 = M) and the apparatus is rearranged as shown in figure b. If the speeds of transverse waves in the two strings are equal the values of M1 and M2 will be respectively
