Question 128 of 142

Two strings with circular cross section and made of same material, are stretched to have same amount of tension. A transverse wave is then made to pass through both the strings. The velocity of the wave in the first string having the radius of cross section R is $\mathrm{v}_1$, and that in the other string having radius of cross section $R / 2$ is $v_2$. Then $\frac{v_2}{v_1}=$
