To increase the frequency from 100 Hz to 400 Hz the tension in the string has to be changed by

A tuning fork of frequency 256 Hz gives 5 beats // s with a vibrating string of a piano. The beat frequency decreases to 2, when tension in the string is slightly increased. What was the frequency of the piano string before increasing the tension ?

The vibrational frequency of a string is 300 Hz. The tension in the string is made twice and the length of the string is changed in such a way that it vibrates with a frequency of 600 Hz. What will be the ratio of new length to original length ?

Two sitar strings A and B are slightly out of tune and produce beats of frequency 5 Hz. When the tension in the string B is slightly increased, the beat frequency is found to reduce to 3 Hz. If the frequency of string A is 427 Hz, the original frequency of string B is

Two sitar strings A and B are slightly out of tune and produce beats of frequency 5 Hz. When the tension in the string B is slightly increased, the beat frequency is found to reduce to 3 Hz. If the frequency of string A is 427 Hz, the original frequency of string B is

Two identical stringed instruments have frequency 100 Hz . If tension in one of them is increased by 4% and they are sounded together then the number of beats in one second is

Two sitar strings A and B playing the note 'Dha' are slightly out of tune and produce beats of frequency 5 Hz, The tension of the string B is slightly increased and the beat frequency is found to decrease to 3 Hz. What is the original frequency of B if the frequency of A is 427 Hz ?
