Answer:

Possible options:

A. Moment of inertia

B. Angular acceleration

C. Center of mass

D. Torque

Answer is B. Angular acceleration

Explanation:

Angular acceleration is the time rate of change of angular velocity. In three dimensions, it is a pseudovector. In SI units, it is measured in radians per second squared (rad/s2) and is usually denoted by the Greek letter alpha (α).

The angular acceleration should be with respect to the shorter pencil and it should be larger.

What is angular acceleration?

Angular acceleration refers to the time that shows the rate of change with respect to the angular velocity. In terms of three dimensions, it represents the pseudovector. Also, in SI units, it should be measured in radians per second squared and should be denoted by the  Greek letter alpha (α).

Therefore, The angular acceleration should be with respect to the shorter pencil and it should be larger.
