What is the approximate sum of the following two vectors: magnitude 5 at 0 ° and magnitude 10 at 180 ° ?
A) magnitude 5 at 90 °
B) magnitude 5 at 180 °
C) magnitude 15 at 90 °
D) magnitude 15 at 180 °

Question

Quizplus · Accepted Answer

The vectors are in opposite directions along the same line. The magnitude 10 vector at 180° effectively subtracts 5 from the magnitude 5 vector at 0°, resulting in a vector of magnitude 5 at 180°.
