Question When two tuning forks are sounded together \( x \) beats/sec are heard and frequency of \( A \) is \( n \). Now when one prong of \( B \) is loaded with a little wax, the number of beats per second decreases. The frequency of fork B is:
(A) \( n+x \)
(B) \( n-x \)
(C) \( n-x^{2} \)
(D)  \( n-2 x \)📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
