Question

Which of the following pair will not be attracted or deflected by the charge plates in an electric field?

• A. An alpha particle and a neutron
• B. A beta particle and a positon
• C. A quark and a deuteron
• D. A proton and gamma radiation
• E. Gamma radiation and a neutron

Answer 1

Answer: (E)

Gamma radiation and a neutron

Alpha particles are positively charged, beta particles are negatively charged, positron and deuteron are also positively charged while neutron and gamma radiation is electrically neutral. This means that other particlescan be deflected by electric fields excepted gamma radiation and neutrons which are not deflected.
