Question

water filled in a flask upto height 0.2m the bottom of radius is 0.1 find the force exerted by water?

Answer 1

The water flask is cylindrical.
Height, h = 0.2m
bottom radius, r = 0.1m

Volume of water, V = πr²h = π×0.1²×0.2 = 0.00628 m³
density of water, d = 1000 kg/m³
mass of water, m = Vd = 0.00628×1000 = 6.28 kg
g = 9.8 m/s²

force exerted by water = mg = 6.28×9.8 = 61.54 N
