Angular speed, acceleration and displacement

Angular acceleration is defined as the rate of change in angular velocity with respect to time. It has both magnitude and direction. So, it is a vector quantity.

Angular Position

Before diving into angular position, one should understand the basics of position and its importance along with usage in day-to-day life. When one talks of position, it’s always relative with respect to some other object. For example, position of earth with respect to sun, position of school with respect to house, etc. Angular position is the rotational analogue of linear position.

Question

The figure shows three 0.01 kg particles
that have been glued to a rod of length L= 6 cm and

we remove one particle (that is, 33% of the mass), by
what percentage does the rotational inertia of the assembly around the rotation axis
decrease when that removed particle is
(a) the innermost one?
(b) the outermost one?
