At a specific instant emission of radioactive compound is deflected in a magnetic field . The compound can emit
(i) electron (ii)protons(iii)`He^(2+ )`(iv) neutrons
The emission at instant can be

Options

A. `i, ii, iii`
B. `i, ii, iii, iv`
C. `iv`
D. `ii, iii`

Answer

A

Explanation

Through the compound can emit all the four particle namely electrons, protons, `He^(2+)` and neutrons. But the particle neutron can't be deflected in the magnetic field, since it is a neutral particle. Hence, the deflectable particles are protons, electrons and `He^(2+)`.
