If vibrations of a string are to be increased by a factor of two, then tension in the string must be made

If an addition of 75 kg wt to the vibrating string rises the pitch is an octave of the original pitch, then the tension in the string is

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 frequency of fundamental mode of vibration of a stretched string fixed at both the ends is 25 Hz. If the string is made to vibrate with 7 nodes , what is the frequency of vibration ? If the length of string is 3 m , what is the frequency of the 4th harmonic ?

Speed of transverse wave on string is v . If tension is increased by factor of 4 and radius of the string is increased by factor of 2, then the new wave speed will be :

Speed of transverse wave on string is v . If tension is increased by factor of 4 and radius of the string is increased by factor of 2, then the new wave speed will be :

Speed of transverse wave on string is v . If tension is increased by factor of 4 and radius of the string is increased by factor of 2, then the new wave speed will be :

A tuning fork of frequency 256 Hz is producing 5 beats/sec with the vibrating string of a sitar. On increasing the tension in the string, the beat frequency becomes 3 beats/sec. The initial frequency of sitar before increasing the tension is

The frequency of vibration of a string depends on, (i) tension in the string (ii) mass per unit length of string, (iii) vibrating length of the string. Establish dimension the relation for frequency.

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 ?
