Question

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

Accepted Answer

The two forces that act on the body are Downward direction weight of the body Upward direction upthrust of the liquid ii Magnitude of the forces acting on the body can determine whether the body will sink or float The body will sink if the weight of the body is greater than the upthrust acting on it whereas the body will float if the weight of the body is equivalent to or lesser than the upthrust acting on it iii a The net force acting on the body when it sinks is the weight of the body itself b The net force acting on the body when it floats is the upthrust due to the liquid
