Which of the following is/ are affected by the electric and magnetic fields?I. Alpha particleII. Beta particleIII. Gamma rays
Correct answer: C. I and II
- A. I only
- B. III only
- C. I and II
- D. II and III
Explanation
Alpha particles (Option I) and beta particles (Option II) are charged particles, hence they are affected by electric and magnetic fields. Gamma rays (Option III), however, are neutral and are not influenced by these fields. Therefore, Option C is correct as it correctly identifies both alpha and beta particles as being influenced by electric and magnetic fields. Options A and B are incorrect because they either ignore the effect on alpha particles or incorrectly assert that gamma rays are affected. Option D is incorrect as it includes gamma rays, which are not affected by the fields.

About Radioactive Decay
Radioactive decay is the spontaneous transformation of unstable nuclei, described by decay constant, activity, half life and the exponential decay law. Work includes alpha, beta and gamma emissions, decay equations and remaining nuclei, with half life distinguished from the time required for complete decay.
