What is the angle between two vector forces if the magnitude of resultant force is minimum?

Expert Answers

An illustration of the letter 'A' in a speech bubbles

For the magnitude of the resultant of two forces to be minimum, the angle between the two vectors that represent the forces should be 180 degrees. In other words the forces should be in the opposite direction.

If the forces are F1 and F2, the magnitude of the resultant force when the angle between the vectors representing the forces is 180 degrees, is equal to |F1 - F2|.
