If the magnitude of sum of two vectors is equal to the magnitude of difference of the two vectors the angle between these vectors is 45∘45^\circ 180∘180^\circ 0∘0^\circ 90∘90^\circ

Multiple Choice Options

  • A 45 o
  • B 180 o
  • C 0 o
  • D 90 o

Step-by-Step Verified Solution

Let the two vectors are A _ and B _ . Given that, | A _ + B _ | = | A _ _ B _ | _ A 2 + B 2 + 2 A B cos _ _ = A 2 + B 2 _ 2 A B cos _ _ _ 4 A B cos _ _ = 0 _ 4 A B � 0 _ cos _ _ = 0 _ _ = 90 o
