Question

Write two similarities between an electron and a beta particle.

Answer 1

Same Rest Mass: Both particles possess the exact same rest mass of approximately 9.1 × 10⁻³¹ kg (or roughly `1/1840` of the mass of a proton).

Same Electric Charge: Both particles carry a single unit of negative electric charge, which is exactly −1.6 × 10⁻¹⁹ C (represented symbolically as −e).
