MCQ
As the speed of a particle increases, its rest mass:
  • A
    Increases.
  • B
    Decreases.
  • ✓
    Remains the same.
  • D
    Changes.
✓

Answer

Correct option: C.
Remains the same.

Rest mass of a particle $m_0$ is universally constant. It doesn't vary with the frames as well as with the speed with which the particle is moving.
