Question

What are the magnitude and direction of vector B if it has no x-component?

a) Magnitude: B, Direction: 0 degrees
b) Magnitude: B, Direction: 90 degrees
c) Magnitude: 0, Direction: B degrees
d) Magnitude: B, Direction: 180 degrees

Answer 1

If the vector B has no x-component and the y-component is non-zero, its magnitude and direction would be determined by the y-component of the vector.

Step-by-step explanation:

The magnitude and direction of vector B, if it has no x-component, would depend on the y-component. If the y-component is non-zero, then vector B would have a magnitude and direction determined by the y-component. If the y-component is zero, then vector B would have a magnitude of 0 and its direction would be undefined.
