Question asked by Filo student
4.4.5 Cause of Buoyant Force Liquid in a container exerts pressure at all the points inside it and in all directions. The pressure increases with depth inside the liquid but remains same at the points on a horizontal level. When a body is immersed in the liquid, it experiences pressure from all the directions as shown in Fig. 4.14. Since, pressure at a horizontal level remains same, therefore, the forces exerted by the liquid on left and right sides of the body are equal and opposite, thus, cancel the effect of each other. But, the force exerted on the upper face of the body in downward direction is less than the force exerted on the lower face in upward direction because pressure on
