Q:

The sum of two vectors of fixed magnitudes has its minimum magnitude when the angle between these vectors is

Accepted Solution

A:
Answer:   180°Step-by-step explanation:When the angle between the vectors is 0°, the magnitudes add, so the sum will be a maximum. When the angle between the vectors is 180°, the resultant has a magnitude equal to the difference of the vector magnitudes. For angles between those extremes, the sum will be somewhere between those extremes.The sum is a minimum when the angle between the vectors is 180°.
