Question

21. The magnitude of the resultant of the two equal
vectors is equal to the magnitude of the either
vector, what is the angle between two vectors?​

Answer 1

Answer:

Two vectors (inclined at any angle) and their sum vector from a triangle. Thus, the vector →A and →B of same magnitudes have the resultant Vectors →R of the same magnitude. In this case angle between →A and →B is 120∘.
