(C) According to the theory of special relativity,the relativistic mass $m$ of an object moving with velocity $v$ is given by the formula:$m = \frac{m_0}{\sqrt{1 - \frac{v^2}{c^2}}}$Given that the speed $v = 0.8 c$,we substitute this value into the equation:$m = \frac{m_0}{\sqrt{1 - \frac{(0.8c)^2}{c^2}}}$$m = \frac{m_0}{\sqrt{1 - 0.64}}$$m = \frac{m_0}{\sqrt{0.36}}$$m = \frac{m_0}{0.6}$$m = \frac{m_0}{6/10} = \frac{10}{6} m_0 = \frac{5}{3} m_0$Therefore,the mass of the electron at this speed is $\frac{5}{3} m_0$.

An electron with rest mass $m_{0}$ moves with a speed of $0.8 c$. Its mass when it moves with this speed is

Monochromatic light of frequency $6 \times 10^{14} \,Hz$ is produced by a laser. The power emitted is $2 \times 10^{-3} \,W$. How many photons per second on an average are emitted by the source? (Given $h = 6.63 \times 10^{-34} \,Js$)

Consider the figure for photoemission. How would you reconcile this with the law of conservation of momentum? Note that light (photons) has momentum in a different direction than the emitted electrons.
