General Studies I
India-based Neutrino Observatory is included by the Planning Commission as a mega science project under the 11th Five-Year Plan. In this context, consider the following statements:
1. Neutrinos are chargeless elementary particles that travel close to the speed of light
2. Neutrinos are created in nuclear reactions of beta decay
3. Neutrinos have a negligible, but nonzero mass
4. Trillions of Neutrinos pass through human body every second
Which of the statements given above are correct?
|A||1 and 3 only|
|B||1, 2 and 3 only|
|C||2, 3 and 4|
|D||1, 2, 3 and 4|
There are three types of neutrinos. Electron neutrinos (or antineutrinos) are generated whenever protons change into neutrons (or neutrons into protons), the two forms of beta decay.
More than 50 trillion solar neutrinos pass through the human body every second.
