In an electric field, which type of radiation is attracted to the negative plate?

In an electric field, beta radiation consists of high-energy electrons or positrons. Since electrons carry a negative charge, they are attracted to the positive plate of the electric field. However, in the context of the question regarding attraction to the negative plate, it is essential to understand that positrons are the equivalent of positively charged particles emitted in certain forms of beta radiation.

Alpha radiation, on the other hand, is composed of helium nuclei, which are positively charged and would be repelled by the positive plate and attracted to the negative plate. Gamma radiation, being electromagnetic radiation with no charge, is not affected by electric fields at all. Similarly, X-ray radiation, also a form of electromagnetic radiation, remains unaffected by electric fields as it carries no charge.

In this context, the attraction to the positive plate implies that the correct answer focuses on the behavior of charged particles, identifying that beta radiation (specifically the positrons) appears to be where attraction occurs, typically towards the negative plate due to their charge dynamics. However, the key point to note is the movement of charged particles within electric fields, which is crucial for understanding how these different types of radiation respond.
