A. A table
B. A foot ball
C. A pen
D. A book

Answer 1

Answer:

(c) pen

Explanation:

because it has the least mass

Answer 2

Pen has least inertia.

• Inertia is a physical quantity representing the ability to stay at rest or motion until any external force acts on it. This is in association with NEWTON'S 1ST LAW OF MOTION.

• Inertia is directly proportional to mass of the object.

• So, table with maximum mass will have highest inertia.

• Whereas, the pen with least mass will have minimum inertia.
