If the coordinates of the initial point and the end point of a vector is given, the Distance Formula can be used to find its magnitude. resultant force is the force (magnitude and direction) obtained when two or more forces are combined.
Answer:
Fundamental frequency is 200 Hz.
Explanation:
It is given that,
Frequency of the 3rd harmonic is 600 Hz.
Let f is the fundamental frequency. We need to find the value of f. The frequency of third harmonic is given by :

So, fundamental frequency f is equal to :
f = 200 Hz
So, the fundamental frequency of the harmonics is 200 Hz. Hence, this is the required solution.
