Find the equation of the plane passing through (a,b,c) and paralle toteh plne `vecr.(hati+hatj+hatk)=2`. |
|
Answer» Correct Answer - `vecr.(hati+hatj+hatk)=a+b+c` We know that any plane parallel to `vecr.vecn=q` is `vecr.vecn=q_(1)`. Let the required plane parallel to the given plane be `vecr.(hati+hatj+hatk)=q_(1)` `rArr (xhati+yhatj+zhatk).(hatk+hatj+hatk)=q_(1)` `rArr (ahati+bhatj+chatk).(hati+hatj+hatk)=q_(1)` `rArr q_(1)=(a+b+c)`. Hence, the required equation is `vecr.(hati+hatj+hatk)=(a+b+c)`. |
