One end of wires of the same metal and of same length (with radius, r and 2 r ) are joined together. The wire is used as sonometer wire and the junction is placed in between two bridges. The tension T is applied to the wire. If at a junction a node is formed then the ratio of number of loops formed in the wires will be:
A. 1 : 2
B. 2 : 3
C. 3 : 4
D. 4 : 5
