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.
A. `t_1ltt_2`
B. `t_1=t_2`
C. `t_1gtt_2`
D. the information is insufficient to find the relation between `t_1 and t_2`
