Which of the following is not the property of \( \beta \) ray?
- A The ionising power is less than that of alpha particles.
- B The penetrating power is greater than that of alpha particles.
- C It is made of positively charged particles.
- D It is deflected by an electric as well as by a magnetic field.
Answer & Solution
Correct Answer
(C) It is made of positively charged particles.
Step-by-step Solution
Detailed explanation
\(\beta\) rays are composed of high-speed electrons (negative charge) or positrons (positive charge), but they are primarily identified as negatively charged particles. Statement C is incorrect because alpha particles, not standard beta rays, are defined as being made of…
