With reference to the India-based Neutrino Observatory (INO) project, consider the following statements about ‘Neutrino’ and its antiparticle ‘antineutrino’:
1. While Neutrino had a positive charge, antineutrino has negative charge
2. Both Neutrino and Antneutrino have zero mass
Which among the above statements is/ are correct?

Answer: [D] Neither 1 nor 2

The first statement is incorrect because the Neutrino is chargeless , and so is antineutrino. The difference between them is opposite spin. The second statement is also incorrect because have a very small, but nonzero mass. The travel with a speed , just less than the speed of light. They are able to pass thru matter very quickly and so almost undetectable.
