A glass full of water has a bottom of area$20{\text{cm}}^2$ , top of area$20{\text{cm}}^2$ , height 20 cm and volume half a liter. (i) Find the force exerted by the water on the bottom (ii) Considering the equilibrium of the water; Find the resultant force exerted by the sides of the glass on the water. $\left[\text{Atomspheric}\text{pressure}=1.0\times {10}^5{\text{Nm}}^{-2},\text{Density}\text{of}\text{water}=1000{\text{kgm}}^{-3}\text{and}\text{g}=10{\text{ms}}^{-2}\right]$
