Question

If the eastward component of vector A is equal to the westward component of vector B and their northward components are equal. Which one of the following statements about these two vectors must be correct?a. vector A is parallel to vector Bb. vectors A and B point in opposite directionsc. vector A is perpendicular to vector Bd. the magnitude of vector A is equal to the magnitude of vector Be. the magnitude of vector A is twice the magnitude of vector B

Answer 1

Answer:

D

Explanation:

The vector have equal but opposite horizontal components and their northward components are the same then the magnitude of the vectors A and B are going to be same though their direction will be different. The values of the vector A and B can be calculated by using Pythagoras theorem

summing the squares of their components which should yield the values.
