A steel ball (density ρsteel = 7200 kg/m 3 ) is placed in an upward moving liquid AI (density ρal = 2360 kg/m 3 , viscosity μAl = 1 × 10 -3 Pa.s and Reynolds number = 5 × 10 5 ). The force (F) exerted on the steel ball is expressed as F = fπR 2 (ρAl V 2 /2) where, f is friction factor (= 0.2), v is the velocity of liquid AI and R is the radius of steel ball. The force exerted on the steel ball is
