A small sphere with radius r and density p falls at a speed v through a fluid of density and coefficient of viscosity n The dimensions of n are ML T 1 If the friction force F opposing the motion is proportional to V it could also be proportional to Select an answer A B C but independent of r nr but independent of p np but independent of p
