The correct Answer is:
To solve the question regarding the deflection of radiation from a naturally occurring radioactive substance in a magnetic field, we can follow these steps: ### Step 1: Understand the Nature of Radiation - **Alpha rays** are positively charged particles (helium nuclei, \( ^4_2He \)). - **Beta rays** are negatively charged particles (electrons, \( e^- \)) or positively charged particles (positrons, \( e^+ \)). ### Step 2: Analyze the Effect of a Magnetic Field - When charged particles move through a magnetic field, they experience a force that causes them to deflect. The direction of deflection depends on the charge of the particle: - **Alpha particles** (positive charge) will deflect in one direction. - **Beta particles** (negative charge) will deflect in the opposite direction. ### Step 3: Consider the Deflection in One Direction - If the question states that the radiation is seen after deflection in one direction, it implies that the radiation consists of either alpha or beta particles, but not both at the same time in that specific direction. ### Step 4: Evaluate the Options - **Option a:** Only alpha rays - This is possible if only alpha particles are present. - **Option b:** Only beta rays - This is also possible if only beta particles are present. - **Option c:** Both alpha and beta rays - This is unlikely since they would deflect in opposite directions. - **Option d:** Either alpha or beta rays - This is a valid option since it allows for the presence of either type of radiation. ### Conclusion Based on the analysis, the correct answer is **Option d: Either alpha or beta rays**. ---
