Answer:
a)1600HZ,b)3N
Explanation:
a)If 1N=200HZ so,2N×8N
2×8=1600HZ
b)If 1N=200HZ so,600HZ/2N
600/2=3N

Answer:
When the tension is increased to 8N the frequency will be 800Hz.
The tension needed to produce a note of frequency 600HZ.
Explanation:
According to the formula,
where,
f is the frequency,
T is the tension and
L is the length of the string.
Now,
It is given,
plucked string is 400HZ and the tension is 2N.
Case-(a)
when the tension is increased to 8N the frequency will be 800Hz.
Case-(b)
When the frequency will be, 600Hz.
Square both the side,
The tension needed to produce a note of frequency 600HZ.
