Question

Which of the following has the largest inertia?

• A. A pin
• B. An ink pot
• C. Your physics book
• D. Your body

Answer 1

The correct option is D

Your body

Explanation for the correct option

(D): Your body

1. As we know that the inertia of a body depends on the mass of the body, the higher the mass higher will be the inertia of the body.
2. Mass of a pin is less than the ink pot while that is less than the physics book which is lower than the body.

Explanation for the incorrect option(s)

(A): Mass of the body is higher than the pin thus the inertia of a body is higher.

(B): Mass of the body is higher than the ink pot thus the inertia of a body is higher.

(C): Mass of the body is higher than the physics book, thus the inertia of a body is higher.

Hence, your body has the largest inertia. Hence option (d) is correct.
