Which of the following is a vector
Which of the following is a vector
Open in App
Solution
The correct option is D None of these
Surface tension is a scalar insofar as it is always oriented parallel to the surface.In higher classes we say moment of inertia is a tensor quantity but in 11th class it is given that moment of inertia is a scalar quantity.
We can put the walls of our container anywhere inside the gas, and the force per unit area (the pressure) is the same. Therefore, pressure is a scalar quantity.
hence option D is correct.
