Two wires A and B, having identical geometricla construction, are stretched from their natural length by smal but equal amount. The young modulus of the wire are `Y_A and Y_B` whereas the densities are `rho_A and rho_B`. It is given that `Y_AgtY_B and rho_Agtrho_B A transverse signal started at one end takes a time `t_1` to reach the other ennd for A and `t_2` for B.

Two wires A and B have the same length and area of cross section. But young's modulus of A is two times the young's modulus of B. Then what is the ratio of force constant of A to that of B?

A: Two wire A and B having equal cross sections made from the same material. The length of A is twice to the length of B, hence the increase in length of A is twice to the increase in length of B for a given same weight. R: Increase in length of wire proportional to its length for a given same length.
