To develop this problem we require the concepts related to Frequency and their respective way of calculating it.
The formula to calculate the frequency is given by

Where,


For fundamental mode, wavelength is equal to 4 time the length.
Then,

Replacing in the first equation,


Therefore the frequency is 96.12Hz
Answer:
The center mass (Xcm) of the two mass = (M₁X₁ + M₂X₂)/(M₁ +M₂)
Explanation:
let the first mass = M
let the position of second = M
False , (No) because if its a regular floor it will more likely break because of the flat surface but if it is concrete then it has more of a chance because it has edges and dents which will help prevent it from breaking.
