NDA Maths Mock Test – 01 – Q70

Let the plane (2x)/(k) + (2y)/(3) + (z)/(3) = 2 pass through the point (2, 3, -6). What are the direction ratios of a normal to the plane?

• < 1, 2, 3 >
• < 3, 2, 1 >
• < 2, 3, 6 >
• < 6, 3, 2 >

Gi√en, equation of plane Z + Ed + £ = 2 and pass through the point (2, 3, —6) the point
i satisfy, then equation of the plane
