Four tuning forks of frequencies 200,201,204 and 206 Hz are sounded together. The beat frequency will be

Three tuning forks of frequencies 248 Hz, 250 Hz, 252 Hz, are sounded together.The beat frequency is,

Two tuning fork of frequency 100 Hz and 105 Hz are sounded together. The time interval between the successive waxing of sound will be

20.Two tuning forks have frequencies 200Hz and x.When they are sounded together 4 beats/ sec are heard.The value of x is

Two tuning forks A and B of frequency 512 Hz are sounded together produce 5 beats/s. If the fork A is thin loaded with a piece of wax and found that beats occur at shorter intervals. Then the natural frequency of A will be

The frequecies of tuning forks A and B are respectively 5% more and 3% less than the frequency of tuning fork C. When A and B are sounded together 8 beats/second are heard. Then the frequency of the tuning fork B will be
