Q. A particle having almost zero mass and exactly zero charge is

MHT CETMHT CET 2008

Solution:

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 $1838 m_{e}$ mass.
So, the required answer is neutrino.
