Physics Question from JEE Main 2026 · 28 January, Shift 2

Two tuning forks $A$ and $B$ are sounded together giving rise to $8$ beats in $2 \, \text{s}$. When fork $A$ is loaded with wax, the beat frequency is reduced to $4$ beats in $2 \, \text{s}$. If the original frequency of tuning fork $B$ is $380 \, \text{Hz}$, find the original frequency of tuning fork $A$.

% Given Given: $f_B = 380 \, \text{Hz}$
