Question

A student has four balls – table tennis ball, tennis ball, cricket ball and a football. The correct ascending order of inertia is : (i) table tennis ball, tennis ball, football, cricket ball (ii) cricket ball, football, tennis ball, table tennis ball (iii) table tennis ball, football, cricket ball, tennis ball (iv) football, cricket ball, table tennis ball, tennis ball

Answer

(i) table tennis ball, tennis ball, football, cricket ball

Reason — As the property of inertia is because of the mass of the body. Greater the mass, greater the inertia. Ascending order of mass is table tennis ball < tennis ball < football < cricket ball, hence ascending order of inertia is table tennis ball < tennis ball < football < cricket ball.
