For the given reaction, the particle \(X\) is:
\({ }_6^{11} \mathrm{C}\rightarrow { }_5^{11}\mathrm{B}+\beta^{+}+X\)
1. neutron
2. anti neutrino
3. neutrino
4. proton
In any fission process the ratio
1. Greater than 1
2. Depends on the mass of the parent nucleus
3. Equal to 1
4. Less than 1
Fission of nuclei is possible because the binding energy per nucleon in them:
1. | decreases with the mass number at low mass numbers |
2. | increases with the mass number at low mass numbers |
3. | decreases with the mass number at high mass numbers |
4. | increases with the mass number at high mass numbers |
Nuclear – fission is best explained by:
1. Liquid droplet theory
2. Yukawa - meson theory
3. Independent particle model of the nucleus
4. Proton-proton cycle
For the nuclear reaction:
The blank space can be filled by:
1.
2.
3.
4.
emitted one particles, then it will become:
1.
2.
3.
4. None of these
When X → \(N_{7}^{14}\) + 2\(\beta^{-} \) then the number of neutrons in X will be:
1. 3
2. 5
3. 7
4. 9
If in a nuclear fusion process. the masses of the fusing nuclei be \(m_1\) and \(m_2\) and the mass of the resultant nucleus be \(m_3,\) then:
1. | \( m_3=\left|m_1-m_2 \right|\) | 2. | \( m_3<\left ( m_1+m_2 \right ) \) |
3. | \( m_3>\left ( m_1+m_2 \right ) \) | 4. | \( m_3=\left ( m_1+m_2 \right ) \) |
A nucleus represented by the symbol has:
1. | Z protons and A –Z neutrons |
2. | Z protons and A neutrons |
3. | A protons and Z –A neutrons |
4. | Z neutrons and A –Z protons |
