Textbook Question
Chapter 3, Problem 1FTD

Under what conditions is the magnitude of the vector sum A + B equal to the sum of the magnitudes of the two vectors?

Expert Solution & Answer
Check Mark
To determine

To explain:

The conditions for the magnitude of the vectors sum A+B is same as the sum of magnitudes of vectors A and B .

Explanation of Solution

The statement satisfies under the following conditions:

  • The two vectors A and B are collinear which means the vectors should lie on the same plane in the same or opposite direction.
  • Simply add the magnitudes of vectors A and B thereby the resultant sum vector also lies on the same plane.

Conclusion:

The condition exists for the vectors passing in same or opposite direction.
