Hope this helps you. Do mark me as brainliest.
The angular velocity is defined as "the angle changing over time."
From the given of the problem:
m = 100g
rate of revolution = 50 rev / min
Therefore, using the formula:
angular velocity = rate of revolution x 2*pi / revolution
Substituting:
angular velocity = (50 revs / min) x ( 2*pi radians / rev ) = 100*pi radians / min
As you can see, mass is not a part of the equation for solving the angular velocity therefore the amount of mass does not affect its value.
The neutron is uncharged. That's why it was
given a name built on "neu" from "neutral".
