Damp clothes are dried in spin dryers by the action of
A). Centripetal forces
B). Centrifugal forces
C). Central forces
D). Non central forces
Centrifugal forces
The spin dryer is probably the most familiar centrifuge. The spin dryer of a washing machine removes excess water from the clothing by rotating at a high speed. The high speed of rotation creates a high centrifugal force for the water in the clothing which causes it to be pulled to the outside of the spinning portion of the washing machine and away from the clothes.
