Find the Drag force....

IIT JEE Help › Physics Olympiad questions › Find the Drag force....

A cylinder of mass M and radius R moves with speed v through a region of space that contains particles of mass m, that are at rest. In unit vol., 'n' of these particles are present. Cylinder moves in a direction perp to its axis. Assume m<<M, and that the particles do not interact with each other, what is the drag force per unit length on the cylinder?
