Each of the two strings of length $\displaystyle 51.6$ cm and $\displaystyle 49.1$ cm are tensioned separately by $\displaystyle 20$ N force. Mass per unit length of both the strings is same and equal to $\displaystyle 1 \mathrm{~g} / \mathrm{m}$. When both the strings vibrate simultaneously the number of beats is :
Official answer
(3)
$\displaystyle 7$
