Radiations of intensity $0.5 \mathrm{W}/{\mathrm{m}}^2$ are striking a metal plate. The pressure on the plate is

• A

  $0.166\times {10}^{-8 }\mathrm{N}/{\mathrm{m}}^2$

• B

  $0.332\times {10}^{-8} \mathrm{N}/{\mathrm{m}}^2$

• C

  $0.111\times {10}^{-8} \mathrm{N}/{\mathrm{m}}^2$

• D

  $0.083\times {10}^{-8} \mathrm{N}/{\mathrm{m}}^2$
