Question

An iron ball and aluminum ball has same mass

• A. inertia of iron is greater than aluminum
• B. both balls have same inertia
• C. inertia of iron is less than that of aluminum
• D. none of these

Answer 1

The correct option is B

both balls have same inertia

Explanation for the correct option

(B): both balls have same inertia

1. As per the given information, both iron and aluminum ball has the same mass.
2. Inertia depends upon the mass of an object.
3. Hence, an iron ball and an aluminum ball have same inertia because they have the same mass.

Hence, an iron ball and the aluminum ball have the same inertia. Hence option (b) is correct.
