Answer:
The maximum frequency of revolution is 3.6 Hz.
Explanation:
Given that,
Mass = 8 kg
Distance = 400 mm
Tension = 800 N
We need to calculate the velocity
Using centripetal force

Where, F= tension
m = mass
v= velocity
r = radius of circle
Put the value into the formula



We need to calculate the maximum frequency of revolution
Using formula of frequency

Put the value into the formula


Hence, The maximum frequency of revolution is 3.6 Hz.
I believe it is A. Just don't hold me down on that. :D
