Question

If a cricket ball and a stone have same mass then​

Answer 1

If the mass of a cricket ball and a stone are the same then the moment of inertia has to be the same.As a result, both have the same inertia.

Answer 2

Although your question is incomplete, you may be referring to:

If a cricket ball and a stone have the same mass, then:

A. Both have the same inertia

B. Both have the same momentum

C. Both have different inertia

D. Both have different momentum

What is inertia?

• Inertia is the tendency of a body to remain in its state of motion or rest and resist change in its state.
• It is a measure of the mass of a body.

• It can be the inertia of rest, motion, or direction.

What is momentum?

• Momentum is the product of mass and velocity.
• Mathematically, p = m × v
• It is a vector quantity.

• Now it is given that both stone and the cricket ball have the same mass.
• Since inertia is a measure of the mass of a body and does not depend on any other factor, so we can say both objects have the same inertia.
• On the other hand, momentum also depends on the velocity of the body.
• Since we do not have information on either body's velocity, thus we cannot comment on their momentum.

Hence, the most appropriate option is A. both have the same inertia.
