Answer:
v = 72.54 m/s
Explanation:
We have,
Length of a guitar string is 0.62 m
Frequency of a guitar string is 234 Hz
For guitar string,

The velocity of the wave in the string is given by :

So, the velocity of the waves in the string is 72.54 m/s.
Part a)
Magnitude of electric field is given by force per unit charge

F = qE


PART C)
Gravitational force is given by



PART d)
Ratio of electric force to weight
