- Correct answerB
- C
- D
Solution
Given,
will be the plane containing the line and parallel to .
So, the normal vector of plane parallel to and is given by,
Hence, the equation of plane will be,
which passes through origin,
So,
Now solving,
distance of point from .
Point of intersection will be of given planes will be,
Hence, distance
Option (B) is correct.
Hence, the correct answer is option: 'B'.
