The vectors a lies in the plane of vectors b and c , then

Options

  1. A[ a b c ]
  2. B[ a b c ]= b c
  3. C[ a b c ]=0
  4. D[ a b c ]=-1

Correct answer

C. [ a b c ]=0

Step-by-step solution

Vector a lie in the plane of vector b and c . a,b, c are coplanar vectors. Hence, a aligned ( b c ) & =0 [ a b c ] & =0 aligned
