The charge-to-mass ratio r of a particle is given by the equation shown. r = charge on particle / mass of particle The value of r is determined for an α-particle, a β⁺ particle and a proton p. Which list shows the particles in order of increasing magnitude of r from left to right?
Aα → β⁺ → p
Bα → p → β⁺
Cp → α → β⁺
Dp → β⁺ → α
✓ Correct answer
B: α → p → β⁺
