Question

An object moves in honey and milk. In which of the two the frictional force will be more?

  1. Milk
  2. Honey
  3. Both will have the same value
  4. Cannot say

hintHint:

When the object moves in honey and milk, the object creates more frictional force with honey as it is more viscous than the milk.
The ease of deformation or movement of a fluid increases with decreasing viscosity. Thus there exists less friction.

The correct answer is: Honey


    Among the two, the frictional force will be more in case of honey.
    • The frictional force applied to a liquid is fluid friction.
    • The frictional force depends on the nature of the liquid which can be defined by viscosity/ viscous drag, or fluid friction are all terms used to describe this internal flow resistance.
    • The more viscous liquid requires more liquid friction.
    • As compared to milk, honey creates more frictional force as it is more viscous than milk. 
    • As a result, honey is "thick," having a higher viscosity, compared to milk, which is "thin," having a lower viscosity.
