Magnitude of vector a minus vector b is equals to magnitude of vector equal to magnitude of vector b then angle between vector a and vector b east
Answers
Answer:
Explanation:
The required angle is 120 degree. Draw a triangle ABC with each sides equal. Now let AB represent the first vector in magnitude and direction and let BC represent the second vector in magnitude and direction. Now by triangle law AC is the resultant in magnitude and direction. According to this question AB=BC=AC (magnitudes). It happens when ABC is an equilateral triangle. Now since each interior angle is 60 degree , angle between AB and BC is 120 degree ( you have to produce AB cause that is the definition of angle between two vectors). Hope it helped.
Answer:
Magnitude of vector A+B is equal to magnitude of A is equal to Magnitude of B then angle between A&B is? Resultant of two vectors A and B is R. now magnitude of the vector is doubled keeping direction same, then magnitude of the resultant becomes /B/. Angle between vector A and B is 120 degrees.
