Task 1 (a) The hydrostatic thrust force, F; exerted by a fluid with density p acting on a submerged plane surface of area A whose centroid is a distance h from the free surface of the fluid is given by: Fr = pghA Show that this formula has dimensional homogeneity. (b) The period T of a pendulum of length 1 is given by [ T =21 | g Show that this formula has dimensional homogeneity
