Question

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 the strings. The velocity of the wave in the first string having the radius of cross section $R$ is $v_1$ , and that in the other string having radius of cross section $R/2$ is $v_2$ . Then, $\frac{v_2}{v_1}$ is:

A
$4$
B
$\sqrt{2}$
C
$8$
D
$2$
