Question

Two identical bullets are fired. The first one is fired from a gun and the second one from a rifle. The rate of change of momentum of both bullets is same. Which weapon will recoil with a greater force?

• A. Gun
• B. Rifle
• C. Both A and B
• D. Can’t be determined

Answer 1

The correct option is C

Both A and B

By Newton’s third law of motion, both the weapons will recoil with the same force, as the force applied by both the weapons on the bullet is same. The force applied by bullet on the each weapon will be same by action reaction pair.
