0.3847 m/s

Explanation:

= Intensity = $\dfrac{P}{A}=\dfrac{P}{\pi r^2}$

d = Diameter = 20 cm

r = Radius = $\dfrac{d}{2}=\dfrac{20}{2}=10\ cm$

c = Speed of light = $3\times 10^8\ m/s$

s = Distance = 100 m

P = Power = 22 MW

Pressure due to the laser is given by

$P_r=\dfrac{I}{c}\\\Rightarrow P_r=\dfrac{P}{Ac}\\\Rightarrow P_r=\dfrac{P}{\pi r^2c}\\\Rightarrow P_r=\dfrac{22\times 10^{6}}{\pi 0.1^2\times 3\times 10^8}\\\Rightarrow P_r=2.33427\ N/m^2$
