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

The frequency of vibration of string can be increased by

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 ?
