If a proton and antiproton come close to each other and annihilate, energy released will be
1 \(1.5 \times 10^{-10} \mathrm{~J}\)
2 \(3 \times 10^{-10} \mathrm{~J}\)
3 \(4.4 \times 10^{-10} \mathrm{~J}\)
4 None of these
Explanation:
B We know that, Mass of proton \(=\) Mass of anti proton. Hence, Combined mass \((\mathrm{m})=2 \times\) Mass of proton \(\mathrm{m}=2 \times 1.67 \times 10^{-27} \mathrm{~kg}\) \(\mathrm{~m}=3.34 \times 10^{-27} \mathrm{~kg}\) \(\text { Energy }(\mathrm{E}) =\mathrm{mc}^2\) \(=3.34 \times 10^{-27} \times\left(3 \times 10^8\right)^2\) \(=3 \times 10^{-10} \mathrm{~J}\)

In nuclear fission \(0.1 \%\) mass is converted into energy. The energy released by the fission of 1 kg mass will be
1 \(9 \times 10^{16} \mathrm{~J}\)
2 \(9 \times 10^{19} \mathrm{~J}\)
3 \(9 \times 10^{13} \mathrm{~J}\)
4 \(9 \times 10^{17} \mathrm{~J}\)
Explanation:
C Given, mass ( \(\mathrm{m})=1 \mathrm{~kg}\) \(1 \%\) mass converted into energy then mass \(\mathrm{m}^{\prime}=\frac{0.1}{100}=0.001 \mathrm{~kg}\) Energy \((E)=m^{\prime} c^2\) \(=0.001 \times\left(3 \times 10^8\right)^2\) \(=9 \times 10^{13} \mathrm{~J}\)

According to theory of relative mass of an object is
1 Depends on particles
2 Speed of light
3 Volume of object
4 Area of object
Explanation:
B We know \(m=\frac{m_0 c}{\sqrt{1-\frac{v^2}{c^2}}}\) Hence, mass of an object depends upon speed of light.
