Pick up the correct statement from the following. A rubber ball when strikes a wall rebounds but a lead ball of same mass and velocity when strikes the same wall, falls down A. Rubber and lead balls undergo equal changes in momentum B. Change in momentum suffered by lead ball is less that of rubber ball C. Momentum of rubber ball is less than that of lead ball D. None of these

The correct answer is: B. Change in momentum suffered by lead ball is less that of rubber ball.

When a ball strikes a wall, the wall exerts an equal and opposite force on the ball. This force causes the ball to change its momentum. The change in momentum is equal to the product of the mass of the ball and the change in its velocity.

The mass of the lead ball is greater than the mass of the rubber ball. Therefore, the lead ball will experience a smaller change in velocity than the rubber ball. This is because the same force will cause a smaller change in the velocity of a more massive object.

The change in momentum of the lead ball is less than the change in momentum of the rubber ball. This is because the lead ball experiences a smaller change in velocity than the rubber ball.

Option A is incorrect because the change in momentum of the lead ball is less than the change in momentum of the rubber ball.

Option C is incorrect because the momentum of the rubber ball is not less than the momentum of the lead ball. The momentum of the two balls is equal before they strike the wall. After they strike the wall, the momentum of the lead ball is less than the momentum of the rubber ball.

Option D is incorrect because the change in momentum of the lead ball is less than the change in momentum of the rubber ball.
