Beta particles from various radioactive sources all have:
Correct answer: A. The same mass
- A. The same mass
- B. The same charge
- C. The same speed
- D. The same deflection
Explanation
Beta particles are either electrons or positrons. All electrons have the exact same rest mass, and all positrons have the exact same rest mass (which is identical to the electron's). Their charge(+1 or -1), speed, and deflection can vary.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
