Question

When applying the parallelogram rule to two perpendicular vectors that are equal in magnitude, what is the result?

1) The resultant vector is zero.
2) The resultant vector is equal to the magnitude of one of the vectors.
3) The resultant vector is equal to the sum of the magnitudes of the two vectors.
4) The resultant vector is equal to the difference of the magnitudes of the two vectors.

Answer 1

When applying the parallelogram rule to two perpendicular vectors that are equal in magnitude, the resultant vector is equal to the magnitude of one of the vectors.

Step-by-step explanation:

When applying the parallelogram rule to two perpendicular vectors that are equal in magnitude, the resultant vector is equal to the magnitude of one of the vectors. When applying the parallelogram rule to two perpendicular vectors that are equal in magnitude, the resultant vector is equal to the magnitude of one of the vectors.

For example, if we have two vectors A and B that are perpendicular and have equal magnitudes, the resultant vector R will have a magnitude equal to the magnitude of A or B.

The direction of the resultant vector will be along the direction of the vector that has the same magnitude as the resultant vector. So, the correct answer is option 2) The resultant vector is equal to the magnitude of one of the vectors.
