Question

4. A metal plate of area 10+ m² is placed on a
liquid layer of thickness 2x10-m. If the liquid
has coefficient of viscosity 2S.I.units the force
required to move the plate with a velocity of
3cm/s is​

Answer 1

Answer:

We are given that

Area of plate=

Thickness of oil layer=6 mm=

Force=

Velocity= 6 cm/s

We have to find the coefficient of viscosity of liquid.

Substitute the values then we get

Hence, the coefficient of viscosity of the liquid=0.1 poise
