Given:
Point given by the equation: \(\vec a=2\hat i-\hat j-4\hat k\)
Plane given by the equation: \(\vec r.(3\hat i - 4\hat j+12\hat k)-9=0,\)
where the normal vector is: \(\vec n=3\hat i-4\hat j+12\hat k\)
We know, the distance of \(\vec a\) from the plane \(\vec r.\vec n-d=0\) is given by:
the distance of the point \(2\hat i-\hat j-4\hat k\) from the plane.
