  • A When there is a net external force acting on a system of bodies ✔ ✖
  • B When there is no net external force acting on a system of bodies ✔ ✖
  • C When the velocity of the first body is higher than that of the second body ✔ ✖
  • D When two bodies collide in a straight line ✔ ✖
Correct Answer

Explanation

The principle of conservation of linear momentum holds true when there is no net external force acting on a system of bodies. This means that the total momentum of the system before an event (like a collision) is equal to the total momentum of the system after the event.
