Question

Which among the following options are correct?
$A)$ Alpha radiations are positively charged
$B)$ Beta radiation may be positively or negatively charged having no mass
$C)$ Beta radiations are only positively charged having mass
$D)$ Gamma radiations have neither charge nor mass.
A) Only $A$ and $B$
B) Only $A$ and $D$
C) Only $B$ and $D$
D) All $A$, $B$, $C$, $D$

Answer 1

Hint: Alpha radiations, Beta radiations, Gamma radiations all have different properties and behave differently with their surroundings. Gamma rays are a form of Electromagnetic, or EM waves and hence the properties of EM waves apply to them.

Complete step by step solution:
Radiation can be portrayed as energy or particles from a source that propagates through different mediums. Light, warmth, microwaves and wireless interchanges are all types of radiation.

All the different types of radiations present in the universe have some similar and some diverse properties. We will study the properties of the above-mentioned radiations to answer the question.

Now, the first is the Alpha Radiation, caused by Alpha Particles. These particles comprise of two protons and two neutrons and are the heaviest kind of radiation molecule. A considerable lot of the normally happening radioactive materials in the earth, similar to uranium and thorium, emanate alpha particles. These radiations have been proved to have positive charge (through the alpha-particle scattering experiment).
Hence, Statement A is correct.

The second sort of radiation is a Beta Radiation which is said to be a flow of electrons. Now, according to properties of electrons, this kind of radiation will have negative charge, and electrons have a negative charge and almost negligible mass. Keeping these properties of Beta radiations in mind.
We conclude that neither Statement B nor C are correct.

The last radiations mentioned in the question are Gamma radiations, or Gamma Rays. These are a kind of Electromagnetic Waves. Hence, the properties of EM waves will apply to them. EM waves have neither mass nor charge.
Therefore, Statement D is also correct.

Hence, Statement A and D are correct. Therefore, Option (B) is the correct answer.

Note: All EM waves have some common properties which classify them as an EM wave. Other than this, EM waves also have their own Corresponding properties that makes them unique and helps recognize them. These properties are important and come in handy in questions like these.
