Atmospheric Pressure and Liquid Pressure

Force acting on per unit area is called

• (a) non-contact forces

• (b) contact forces

• (c) force

• (d) pressure

Pressure =

• (a) Area / force on which it acts

• (b) force / area on which it acts

• (c) Volume / force on which it acts

• (d) Force / volume on which it acts
