Let the vectors a , b , c and d be such that ( a b ) ( c d )= 0 . Let P ₁ and P ₂ be the planes determined by the pair of vectors a , b and c , d respectively, then the angle between P₁ and P₂ is

Options

  1. A0
  2. B4
  3. C3
  4. D2

Correct answer

A. 0

Step-by-step solution

According to the given condition, we get Normal to the plane P₁ is parallel to a b and normal to the plane P ₂ is parallel to c d . Given that ( a b ) ( c d )=0 ( a b ) |( c d ) Angle between P₁ and P₂ is 0 .
