Question

At a specific instant emission of radioactive compound is deflected in a magnetic field. The compound can emit:

• A. electrons
• B. protons
• C. ${He}^{2+}$
• D. neutron

Answer 1

Answer: (A), (B), (C)

The correct options are
A electrons
B protons
C ${He}^{2+}$

A moving particle with velocity $\overrightarrow{v}$ with a charge ${}^{\prime }{q}^{\prime }$ under magnetic field $\overrightarrow{B}$ feels a force of $F=q(\overrightarrow{v}\times \overrightarrow{B})$

In the given emission of the radioactive compound, the emitted particles deflects in the magnetic field, it simply means the particles have some kind of charge, That's why they are feeling a force under some magnetic field.

Hence the emitted particle can be any particle with any charge on it. The possible emitted particles from a radioactive compound with some charge on them are given in Option $A,B$ and $C$

Hence the correct options are $A,B$ and $C$
