Best answer
The correct choice is (d) False, True

Best explanation: In only sedimentation, terminal velocity of the particle is reached after a certain time. In centrifuge, the particles are thrown radially outwards and they don’t settle down. Hence there is no terminal velocity. Still, the same formula for finding out the velocity in both the processes is used.
