AIIMS 2014 Physics Radioactivity MCQ Question
Type: MCQ-conceptual-Medium-Class 12
At a specific instant emission of radioactive compound is deflected in a magnetic field. The compound can emit
A
electron
B
protons
C
He2+
D
neutrons
Correct Answer
Option C
Detailed Explanation
The correct answer is C) He2+ because helium nuclei, which consist of two protons and two neutrons, are positively charged and can be deflected in a magnetic field due to the Lorentz force acting on charged particles. In contrast, electrons (A) are negatively charged and can also be deflected, while protons (B) are charged as well, but neutrons (D) are neutral and do not experience any deflection in a magnetic field.
