A pressure-pump has a horizontal tube of cross sectional area $\displaystyle 10 \mathrm{~cm}^2$ for the outflow of water at a speed of $\displaystyle 20 \mathrm{~m} / \mathrm{s}$. The force exerted on the vertical wall just in front of the tube which stops water horizontally flowing out of the tube, is :
[given: density of water $\displaystyle =1000 \mathrm{~kg} / \mathrm{m}^3$ ]
Official answer
(4)
$\displaystyle 400$ N
