Is pressure a scalar or a vector ? Give reason. |
|
Answer» Solution :PRESSURE is a scalar quantity . Because at a point fluid pressure is equal in all directions . So it shows that no DIRECTION is needed to show the pressure . MOREOVER `P=(F)/(A)` It is the COMPONENT of the force normal to the AREA under consideration and not (vector) force that appears in the numerator. Hence,pressure is a scalar physical quantity. |
