Find the co-ordinates of the foot of the perpendicular drawn from the origin to the plane 5y+8=0.

Question

Accepted Answer

Correct answer: D. (d) : The equation of plane is 5y+8=0 ∴ Equation of normal to the plane is 5 25y= -8 25 ⇒-y= 85 ∴ Direction cosines of normal drawn from origin to the given plane are (0 ,-1 ,0 ) and d= 85 units ⇒ Coordinates of foot of perpendicular drawn from origin are (0 , -85 ,0 )
