Let θ be the angle between the two vectors A and B such that, |A| = |B|.
Therefore,
R 2 = A 2 + B 2 + 2AB cosθ
=> A 2 = A 2 + A 2 + 2(A)(A) cosθ [since, |A| = |B| = |R|]
=> A 2 = 2A 2 + 2A 2 cosθ
=> cosθ = -1/2
=> θ = 60 degrees
negative sign is not considered becaus eof the modulus sign
The question can only be answered if the MAGNITUDE of the resultant is equal to either. Although this is not stated, if that is the case, the answer is 60 degrees.
Zero.

Yes - if the vectors are at an angle of 60 degrees. In that case, the two vectors, and the resultant, form an equilateral triangle.Yes - if the vectors are at an angle of 60 degrees.

The resultant vector is the vector that 'results' from adding two or more vectors together. This vector will create some angle with the x -axis and this is the angle of the resultant vector.

The direction will change; the magnitude of the resultant force will be less.

Zero degrees. This essentially adds up the forces.

The resultant (sum) of nonconcurrent forces is given by the Law of Cosines, which is the product of the vector sums and their conjugate: C^2 = (A + B)(A + B)*=(AA* + BB* + AB* + A*B)= (AA* + BB* + 2ABcos(AB)) The angle of C is given by sin (C) =A/C sin(AB) angle(C ) is smaller than the angle between A and B, angle(AB).
