Q.

The equation of the plane passing through the point (–1, 3, 2) and perpendicular to each of the planes x + 2y + 3z = 5 and 3x + 3y + z =0, is

View Answer

Correct choice: A

Explanation:

Given, equation of plane is passing through the point (–1, 3, 2)
∴A(x + 1) + B (y - 3) + C (z - 2) = 0 .....(i)
Since plane (i) is perpendicular to each of the planes x + 2y + 3z = 5 and 3x + 3y + z = 0
So, A + 2B + 3C = 0 and 3A + 3B + C = 0.
