The vector equation of a plane is vecr.(...

The vector equation of a plane is `vecr.(hati+2hatj+2hatk) = 12`. Convert it into normal form. Find the d.c.s' of the perpendicular vector drawn from origin to this plane and length of perpendicular.

Text Solution

Verified by Experts

The correct Answer is:
`vecr.(1/3hati+2/3hatj+2/3hatk)=4, d.c's= 1/3,2/3,2/3`, length of perpendicular `= 4`units
