Is Area a Vector Quantity?

Answer 1

no ,area is not a vector quantity bcoz we know that vector quantity consists of both magnitude and direction and area doesn't have a direction .position,displacement,velocity,acceleration,force,weight are the examples of vector quantities. The direction of vector is stated by using square bracket behind its magnitude i.e 10km [N]

Answer 2

Is Area A Vector Quantity

Answer 3

If A and B are two vectors having an angle θ between them, then the magnitude of the area bounded by the two vectors is given be the product of the magnitude of A, magnitude of B and sin θ .

The direction of this area is perpendicular to both A and B.

As the perpendicular to this area can be in two sides one direction is taken to be positive and the other is taken to be negative.

If we move the vector from A to B through the angle θ and the resultant area is taken as positive then the movement of vector from B to A via θ is taken as negative.

Thus an area can be represented by a vector whose magnitude is equal to the magnitude of the area and direction is taken to be perpendicular to the area under consideration.

Thus area is a vector quantity.

this is vector quantity and its direction is orthogonal to surface. it is use as vector quantity in some theory so that we can know the angel between area(surface) and any field, lines etc.......... if u r told that the angle between area and electrical field is 30 than you have to consider that field is making angle 30 with the line orthogonal to surface area... so that we have took it vector quantity , by this calculation can be easy...

Answer 5

No. A vector has a magnitude and a direction. Area does not have a direction.

Answer 6

oh yes it is a vector quantity

Answer 7

no. it is a scalar quantity. a vector quanitity is one that has both magnitude and direction and area doesn't have direction

Answer 8

It is not ordinarily treated as such. However, in some calculus problems, it is useful to treat it as a vector, with direction normal to the surface.

Answer 9

________________________________________________________________________________________
In physics , surface area 'A' is a vector, the direction of surface area vector 'A' is perpendicular to the surface;

Electric flux ,a scalar quantity ,is dot product of electric field E and area vector A

Magnetic flux ,a scalar quantity, is dot product of magnetic field B and area vector A
