A bullet is fired by a light rifle and the other with a heavy rifle by the same force. Which rifle will cause more injury to the shoulder?

Options

  1. ALight rifle
  2. BHeavy rifle
  3. CBoth will cause the same injury
  4. DThe information is insufficient

Correct answer

A. Light rifle

Step-by-step solution

While firing a bullet from a rifle, there will be equal back thrust on light rifle as well as heavy rifle. Due to this, the light rifle will move backwards with greater speed than heavy rifle. That is why light rifle will cause more injury.
