Question
In the above problem, the radiation force on the(A) $3.33 \times 10^{-5} \mathrm{~N}$(B) $5.33 \times 10^{-4} \mathrm{~N}$(C) $7.33 \times 10^{-3} \mathrm{~N}$(D) None of these
Step 1
However, the formula is not clearly stated in the explanation. Let's assume it is given by $F = aP^{b}$, where $F$ is the force, $P$ is the power, $a$ and $b$ are constants. Show more…
