Which of the following statements is not true? (a) Coefficient of viscosity is a scalar quantity (b) Surface tension is a scalar quantity (c) Pressure is a vector quantity (d) Relative density is a scalar quantity

Answer: (c). Coefficient of viscosity, surface tension and relative density have magnitude only: scalars. Pressure P = F/A acts equally in all directions at a point and has no fixed direction, so it is a scalar. So the false statement is (c) Pressure is a vector quantity.

Viscosity & Stokes' Law

Which of the following statements is not true?

Show answer and solution

Answer: (c)

Coefficient of viscosity, surface tension and relative density have magnitude only: scalars.
Pressure $P = F/A$ acts equally in all directions at a point and has no fixed direction, so it is a scalar.
So the false statement is (c) Pressure is a vector quantity.
