The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Understanding the Assertion The assertion states that "the mass of beta particles when they are emitted is higher than the mass of electrons obtained by other means." - Beta particles are essentially high-energy electrons or positrons emitted during radioactive decay. - According to the energy-mass relation (E=mc²), as the energy of a particle increases, its effective mass also increases. ### Step 2: Understanding the Reason The reason states that "beta particles and electrons are both similar particles." - Beta particles (which can be electrons or positrons) are indeed similar to electrons in terms of charge and fundamental properties. - However, the assertion about their mass difference is not primarily due to their similarity, but rather due to the energy they possess when emitted. ### Step 3: Evaluating the Assertion and Reason - Both the assertion and the reason are correct: - The assertion is correct because beta particles can have a higher effective mass due to their high energy. - The reason is correct in stating that beta particles and electrons are similar, but it does not adequately explain why beta particles have a higher mass. ### Conclusion Thus, we conclude that: - Both the assertion and reason are correct. - However, the reason is not the correct explanation for the assertion. ### Final Answer The correct option is B: Both assertion and reason are correct, but the reason is not the correct explanation for the assertion. ---
