The vector equation of the line passing through the point having position vector 2 i + j -3 k and perpendicular to vectors i + j + k and i +2 j - k is

Options

  1. Ar =(2 i + j -3 k )+ (-3 i +2 j + k )
  2. Br =(2 i + j -3 k )+ ( i +2 j - k )
  3. Cr =(2 i + j -3 k )+ (-3 i -2 j + k )
  4. Dr =(2 i + j -3 k )+ (-3 i +2 j - k )

Correct answer

A. r =(2 i + j -3 k )+ (-3 i +2 j + k )

Step-by-step solution

The required equation is aligned & r =(2 i + j -3 k )+ ( i + j + k ) ( i +2 j - k ) & r =(2 i + j -3 k )+ (-3 i +2 j+ k ) aligned
