When two vectors 1 and B are drawn from a common point, the angle between them is
Question:
When two vectors 1 and B are drawn from a common point, the angle between them is Φ.
(a) Using vector techniques. Show that the magnitude of their vector sum is given by √ A2 + B2 + 2ABcosΦ
(b) If A(vector) and B(vector) have the same magnitude, for which value of ϕ will their vector sum have the same magnitude as A(vector) or B(vector)?
