Question No 14 Spherical balls of radius r are falling in a viscous fluid of viscosity n with a velocity v Then what can be said about the retarding viscous force acting on the spherical ball O It is directly proportional to both radius r and velocity v It is inversely proportional to r but directly proportional to velocity v It is directly proportional to r but inversely proportional to v It is inversely proportional to both radius r and velocity v
