Given : V₁ + V₂ is perpendicular to V₁ - V₂
To Find : Condition when it happens
Solution:
V₁ + V₂ is perpendicular to V₁ - V₂
=> Dot product will be zero
=> ( V₁ + V₂) . (V₁ - V₂) = 0
=> V₁² - V₂² = 0
=> V₁²= V₂²
=> | V₁| = |V₂ |
Hence magnitude of both the vectors are equal
and angle can be any between vectors
