Damping force on a spring mass system is proportional to which of the following quantities?(a) Velocity(b) Acceleration(c) Displacement from mean position(d) (velocity)^2
Right choice is (a) VelocityThe explanation is: We know from Stoke’s law that damping force is proportional to velocity of a body. It also depends on the surface area in contact with the source of particles causing damping, like air.
