Because of the equivalence of mass and energy,an electron and a positron,which are two massive particles,can annihilate when they come together to produce two photons,which have no mass.

Quizplus · Accepted Answer

According to the principle of mass-energy equivalence (E=mc²), any mass can be converted into energy and vice versa. When an electron and a positron come together, they can annihilate and the mass of both particles is converted into energy in the form of two photons (gamma rays), which have no mass. Therefore, the statement is true.

Because of the Equivalence of Mass and Energy,an Electron and a Positron,which
