Question

vector F1 is along the positive x-axis. if vector product with another vector vecor F2 is zero , than vector F2 could be

Answer 1

If the cross/vector product of a vector with another vector is a zero vector, then that presents two possibilities. Either on of the vectors is a zero vector or both the vectors are parallel to each other or collinear.

Thus, as per our question, if the cross/vector product of a vector $\boldsymbol{F_1}$ with another vector $\boldsymbol{F_2}$ is a zero, then that would mean that either:

1. one of them is a zero vector, or,

2. both the vectors are parallel to each other or are collinear.

Answer 2

Answer:

Step-by-step explanation:

If the cross/vector product of a vector with another vector is a zero vector, then that presents two possibilities. Either on of the vectors is a zero vector or both the vectors are parallel to each other or collinear.

Thus, as per our question, if the cross/vector product of a vector  with another vector  is a zero, then that would mean that either:

1. one of them is a zero vector, or,

2. both the vectors are parallel to each other or are collinear.
