WebStoke's Law - Problems L1 Physics example Problem based on Stoke's law Question: Assume that a spherical body is flowing through water. The velocity of the body at particular instant is 2 m/s. Find the drag force on the body due to … WebThe free surface of drops or bubbles is spherical in shape. Let, P i = inside pressure of a drop or air bubble P o = outside pressure of the bubble r = radius of drop or bubble. As drop is spherical, P i > P o ∴ excess pressure inside drop = P i − P o ; Let the radius of drop increase from r to r + ∆r so that inside pressure remains constant.
