Answer 2

The area vector is 400i cm².

Given:

A square plate of side 20cm is placed in the YZ plane.

To Find:

The area vector.

Solution:

To find the area vector we will follow the following steps:

As we know,

The area vector is the vector whose magnitude is the area of the plane.

The direction of the area vector is perpendicular to the plane.

The square plate is in the YZ plane so the direction of the area vector is perpendicular to the yz plane means in the x-axis and the vector is i^.

The area of the square plane is the square of the side which is equal to (20)² = 400cm².

And the area vector is 400i cm².

Henceforth, the area vector is 400i cm².
