The wires `A` and `B` shown in the figur, are made of the same material and have radii `r_(A)` and `r_(B)`. A block is mass `m kg` is find between them : If the force `F` is `mg//3`, one of the wires breaks.

The wires A and B shown in Fig. are made of the same material and have radii r_(A) and r_(B) , respectively. The block between them has a mass m . When the force F is mg//3 , one of the wires breaks. Then

The wires A and B shown in Fig. are made of the same material and have radii r_(A) and r_(B) , respectively. The block between them has a mass m . When the force F is mg//3 , one of the wires breaks. Then

Two wires A and B have equal lengths and are made of the same material. But the diameter of A is twice that of wire B. Then for a given load

A composite wire of length 2L is made by joining two different wires A and B having the same length, made of the same material but of different radii r and 2r respectively . The composite wire is vibrating at such a frequency, that the junction of the two wires form a node. If the number of antinodes in the wire A is p and that in the wire B is q, then the ratio p : q is
