Find the coordinates of the foot of the ...

Find the coordinates of the foot of the perpendicular drawn from the origin to the plane `2x-3y+4z-6=0.`

Text Solution

Verified by Experts

The direction ratio of OP are proportional to `2,−3,4`
So, cartesian equation of OP are `x/2​=−y/3​=z/4​=r`
So, the coordinates of P are `(2r−3r,4r) `
It lies on `2x−3y+4z−6=0`
`∴4r+9r+16r−6=0` ...
