The working principle of a washing machine is

  1. centrifugation
  2. dialysis
  3. reverse osmosis
  4. diffusion

Explanation

Option (a) is correct
  • A washing machine works primarily on the principle of centrifugation, which is the process of separating substances of different densities by rapid spinning. During the spin cycle, the drum rotates at high speed, creating a centrifugal force that pushes water out of the clothes through the holes in the drum. This helps remove excess water efficiently.
