An average table tennis ball has a diameter of 3.817 cm. and a mass of 2.674 grams. Assuming that air buoyancy is included, what will be the density of air (in kg/m3) needed to make the table tennis ball float to a depth of h = 7.074 mm, in a liquid with specific gravity of 1.001? Neglect any temperature change that could alter the density of air. Hint: Assume the ball to be a sphere.

Concept explainers

Dimensional homogeneity

The term dimensional homogeneity means that in an equation, the dimensions of each term on both sides are equal, which means the dimensions of the left-hand side (LHS) of an equation are similar to the dimensions of the right-hand side (RHS). For a dimensionally homogeneous equation, the powers of fundamental dimensions will be identical on both sides of the equation.
