At a specific instant emission of radioactive compound is deflected in a magnetic field. The compound can emit (i) electrons (ii) protons (iii) He²⁺ (iv) neutrons The emission at instant can be (a) i, ii, iii (b) i, ii, iii, iv (c) iv (d) ii, iii

Answer: (a). A magnetic field deflects only charged particles. Electrons, protons and He²⁺ are charged; neutrons are neutral and are not deflected. So the deflected emission can be (i), (ii), (iii). So the answer is (a) i, ii, iii.

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

$(i)\ \textit{electrons}\quad (ii)\ \textit{protons}$

$(iii)\ He^{2+}\quad (iv)\ \textit{neutrons}$

The emission at instant can be

Show answer and solution

Answer: (a)

A magnetic field deflects only charged particles.
Electrons, protons and $He^{2+}$ are charged; neutrons are neutral and are not deflected.
So the deflected emission can be (i), (ii), (iii).
So the answer is (a) $i, ii, iii$ .
