Question

Two vectors are equal in magnitude and opposite in direction. What is the magnitude of their resultant vector?

a) Zero.

b) Double the magnitude.

c) Equal to the magnitude of one of the vectors.

d) The sum of their magnitudes.

Answer 1

When two vectors are equal in magnitude and opposite in direction, the magnitude of their resultant vector is zero.

Step-by-step explanation:

The magnitude of the resultant vector when two vectors are equal in magnitude and opposite in direction is zero. This is because when the vectors cancel each other out, the sum of their magnitudes becomes zero. The resultant vector has no magnitude.
