Physics - Sound Wave Question with Solution | TestHub

The frequency of a tuning fork$\mathrm{A}$is$2\%$more than the frequency of a standard tuning fork. The frequency of another fork$\mathrm{B}$is$3\%$less than the frequency of a  standard tuning fork. If$6 \mathrm{beats} {\mathrm{s}}^{-1}$are heard when the two tuning forks$\mathrm{A}$and$\mathrm{B}$are excited, the frequency of$\mathrm{A}$is
