TG EAPCET 2024 (Online) 9th May Morning Shift | Waves Question 10 | Physics

The speed of a transverse wave in a stretched string $A$ is $v$. Another string $B$ of same length and same radius is subjected to same tension. If the density of the material of the string $B$ is $2 \%$ more than that of $A$ then the speed of the transverse wave in string $B$ is

$\sqrt{1.04} \mathrm{~V}$

$\sqrt{1.02} \mathrm{~V}$

$\frac{v}{\sqrt{1.04}}$

$\frac{v}{\sqrt{1.02}}$
