A transverse wave travels on a taut steel wire with a velocity of $\displaystyle v$ when tension in it is $\displaystyle 2.06 \times 10^4 \mathrm{~N}$. When the tension is changed to T, the velocity changed to $\displaystyle v / 2$. The value of T is close to :
Official answer
(2)
$\displaystyle 5.15 \times 10^3 \mathrm{~N}$
