Two identical strings of a stringed musical instrument are in unison when stretched with the same tension. The tension in one string is increased by 1%, the musician hears 4 beat/s, then the frequency of the note when the string were in unison , will be

A

796Hz

B

800Hz

C

804Hz

D

808Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`(Deltan)/(n) = 1/2(DeltaT)/(T)`
`4/n_1 = 1/2xx1/100`
`n_1 = 800Hz.`
