A particle having almost zero mass and exactly zero charge is
- A positron
- B electron
- C neutron
- D neutrino
Answer & Solution
Correct Answer
(D) neutrino
Step-by-step Solution
Detailed explanation
We know that the neutrino is the particle which has almost zero mass and exactly zero charge. Positron has the charge \(+e\) and mass \(m_{e}\) [equal to electron mass].
Electron is a particle which has \(-e\) charge and \(9.1 \times 10^{-31}\) kg mass.
Neutron is a particle which has zero charge and \(1838 \mathrm{~m}_{e}\) mass.
So, the required answer is neutrino.
