When the angle between two vectors of equal magnitude is `2pi//3`, prove that tha magnitude of the resultant is equal to either.

When the angle between two vectors of equal magnitudes is 2/3, prove that the magnitude of the resultant is equal to either.

Resultant of two vector of equal magnitude A is

There are two vectors of equal magnitudes. When these vectors are added, then magnitude of the resultant is also equal to the magnitude of each of the two given vectors. Angle between the vectors is

What will be the angle between two vectors of equal magnitude for their resultant to have the same magnitude as one of the vectors?

If resultant of two vectors of equal magnitude is equal to the magnitude of either vector what is the angle between them?

What is the angle between two vector forces of equal magnitude such that their resultant is one-third of either of the original forces?
