Light having an energy flux of $40 \ Wcm^{-2}$ falls on a non-reflecting surface at normal incidence. If the surface has an area of $20 \ cm^2$,the total momentum delivered (for complete absorption) during $10 \ min$ is:

  • A
    $24 \times 10^{-5} \ kg \ ms^{-1}$
  • B
    $16 \times 10^{-4} \ kg \ ms^{-1}$
  • C
    $102 \times 10^4 \ kg \ ms^{-1}$
  • D
    $1.03 \times 10^7 \ kg \ ms^{-1}$

$A$ pulse of light of duration $100 \ ns$ is absorbed completely by a small object initially at rest. The power of the pulse is $30 \ mW$ and the speed of light is $3 \times 10^8 \ m/s$. The final momentum of the object is:

$A$ parallel beam of light is incident normally on a plane surface absorbing $50\%$ of the light and reflecting the rest. If the incident beam carries $90 \text{ W}$ of power,the force exerted by it on the surface is ($C = 3 \times 10^8 \text{ m/s}$ is the velocity of light in air).
