Draw a diagram to show the forces acting on a body floating in water with its some part submerged. Name the forces and show their points of application. How is the weight of water displaced by the floating body related to the weight of the body itself ?
A body is held immersed in a liquid.
(i) Name the two forces acting on the body and draw a diagram to show these forces.
(ii) State how do the magnitudes of two forces mentioned in part (i) determine whether the body will float or sink in the liquid when it is released.
(iii) What is the net force on the body if it (a) sinks, (b) floats?
