Q.No.2.13: - How would the two vectors of the same magnitude have to be oriented, if they were to be combined to give a resultant equal to a vector of the same magnitude?

Q.No.2.13: - How would the two vectors of the same magnitude have to be oriented, if they were to be combined to give a resultant equal to a vector of the same magnitude?

Ans: - If the angle between two vectors of same magnitude is 120º, the magnitude of their resultant vector is also the same.

This can be proved as follows;
