Light is incident normally on a completely absorbing surface with an energy flux of$25\mathrm{ }\mathrm{W}\mathrm{ }\mathrm{c}{\mathrm{m}}^{-2}$. If the surface has an area of$25\mathrm{ }\mathrm{c}{\mathrm{m}}^2$, the momentum transferred to the surface in$\text{40}\text{min}$time duration will be:
