α, β and γ-rays emitted by a radioactive substance are passed through a region containing a magnetic field at right angles to their path. The energy gained will be:
Correct answer: D. Zero for all of them
- A. Maximum for α-rays
- B. Maximum for β-rays
- C. Maximum for γ-rays
- D. Zero for all of them
Explanation
As the work is done by magnetic field so, according to work energy principle, the energy gained will be zero for all of them.

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.
