Question

Which among the following options is 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: Gama radiation has neither charge nor mass.

• A. Only A and B
• B. Only A and D
• C. Only B and D
• D. All A, B, C and D

Answer 1

Answer: (B)

Only A and D

Alpha ray is the flow of positively charged helium nucleus.

So, statement A is correct.

Beta ray is the flow of electrons. So it has negative charge and almost no mass.

Thus statements B and C are incorrect.

Gamma ray is an electromagnetic wave. So gamma ray has no charge and no mass.

Thus statement D is also correct.
