Question

The viscous force between the adjacent liquid layers is inversely proportional to

the________.​

Answer 1

Answer ⇒   The viscous force between the adjacent liquid layers is inversely proportional to the  distance between two successive layers

_____________________________

Explanation  ⇒ According to the newton's equation of Force of Viscosity, which says that Force between the two layers is directly proportional to the area of constant and also directly proportional to the change in velocity gradient.

Now, If you are asking for Inversely proportional, this means you are saying for dz.

 Since, F = ηAdv/dz

where dv is the change in velocity with change in distance from sea bed between two successive liquid layers.

Thus, we can say that, F is inversely proportional to the distance between two successive layers, when there is an change in velocity for both layers.

Hope it helps.
