Question

two vectors of equal magnitude have a resultant equal to either of them, the angle between them will be​

Answer 1

Two vectors of equal magnitude have a resultant equal to either of them. Then, the angle between them will be 2π/3 radians.

God bless you dear

Answer 2

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∘.
