Verified step by step guidance1
Understand the concept of filtration: Filtration is a process used to separate solids from liquids or gases using a filter medium that allows only the fluid to pass through.
Identify the forces listed: Centrifugal force, electrostatic force, magnetic force, and gravity are all forces that can influence the movement of particles.
Consider the role of gravity: Gravity is a natural force that pulls objects toward the center of the Earth, and it is the primary force that causes the liquid to pass through the filter medium in a filtration process.
Evaluate the other forces: Centrifugal force is used in centrifugation, not filtration. Electrostatic and magnetic forces are not typically involved in the basic process of filtration.
Conclude that gravity is the primary force: In most filtration processes, gravity is the main force that drives the liquid through the filter, separating it from the solid particles.
