A glass full of water has a bottom of area 20 cm2, top of area 20 cm , height 20 cm and volume half a litre.
(a) Find the force exerted by the water on the bottom.
(b) Considering the equilibrium of the water, find the resultant force exerted by the sides of the glass on the water. Atmospheric pressure = 1.0 x 108N/m. Density of water = 1000 kg/m3 and g = 10 m/s2. Take all numbers to be exact.
