A tuning fork produces `6` beats/sec with sonometer wire when its tensions are either `169N` or `196N`. The frequency of that fork is

A

162 Hz

B

190 Hz

C

200 Hz

D

80 Hz

Text Solution

Verified by Experts

The correct Answer is:
A
`(n_1)/(n_2) = sqrt((T_1)/(T_2)) = 13/14 and n - n_1 = 6, n_2 - n = 6`
