Question

One of the following statements is incorrect. Select it. The energy of a particle depends on its momentum and its mass If the decay of a particle is observed in an inertial frame where it is at rest, the total kinetic energy of the daughter particles is equal to the rest energy of the parent particle. If one increases the kinetic energy of a particle by a factor of two, the energy of the particle increases but by less than a factor of two. A particle is to be considered relativistic if its kinetic energy is comparable to or larger than its rest energy. The energy of a particle cannot be less than its rest energy. In an inertial reference frame where a system is at rest, the total energy of the system, which may be a complex bound system of constituent systems, depends only on its mass

Explanation / Answer

The incorrect statement is (3), because if kinetic energy increases then potential energy decreases by the same amount so that energy of the particle is always remains constant according to the law of conservation of energy.
