hi there,
As we know that presure = force/area
nd we also know that force and area don't have any direction only have magnitude..so this is a scalar quantity..a scalar quantity only have magnitude value while vector have both magnitude as well as direction..hence this is a scalar qnt...
thank you

aimonchaudry13ovetnv: force is a scalar???
Avanish010: force=mass*acc...thus force is scalar..
aimonchaudry13ovetnv: acc is vector...
Avanish010: No..
aimonchaudry13ovetnv: can u please elaborate this whole thing i m confused because its written in my book that force is a vector quantity...
Avanish010: sry..Force is a vector quantity because it actually does depend in which direction you apply the force. The force can be seen physically as a push or a pull.
Avanish010: i just gone through a another way..
Avanish010: just like we represent Force vector we easily conclude that it have direction too
Avanish010: acceleration is a vector quantity whose direction and magnitude both can be specified and obeys laws of vector algebra.
Avanish010: F=mass*acc...nd acc is vector so f is a vector qnt.

Pressure is the constant of proportionality between the force applied, and the differential of area.

dF⃗ =−pdA⃗ dF→=−pdA→

Force and area are both vector values however.

If u found the answer useful then please mark it as the brainliest.
