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

Two equal forces have their resultant equal to eitherat what angle are they inclined?
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.
Two equal forces f and f make an angle of 180 with each other the magnitude of their resultant is?
Zero.
What is the resultant of two forces 4N and 5N exerted at an angle 30 degrees between them?

Can the resultant of two vectors of the same magnitude be equal to the magnitude of either of the vector. How?
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.

Define the angle of the resultant vector?
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.

What is the effect on the resultant of increasing the angle between the two forces?
The direction will change; the magnitude of the resultant force will be less.

How do you determine the magnitude and the direction of the resultant of nonconcurrent 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).
