Two wires

W_1

W_2

have the same radius r and respective densities

\rho_1

\rho_2

\rho_2=4\rho_1

.They are joined together at the point O, as shown in the figure. The combination is used as a sonometer wire and kept under tension T. The point O is midway between the two bridges. When a stationary wave is set up in the composite wire, the joint is found to be a node. The ratio of the number of antinodes formed in
