1.	If two tuning fork A and B are sounded together they produce 4 beats per second. A is then slightly loaded with wax, they produce 2 beats when sounded again. The frequency of A is 256. The frequency of B will beA. `250`B. `252`C. `260`D. `262`
Answer» Correct Answer - B `n_a=`known frequency `=256Hz`,`n_B=?` `x=4bps`, which is decreasing after loading (i.e., `xdarr`) Also known tuning fork is loaded so `n_Adarr` Hence `n_Adarr-n_B=xdarr` .(i) correct `n_B-n_Adarr=xdarr` .(ii) Wrong `impliesn_B=n_A-x=256-4=252Hz`
