The equation to the plane passing through P(2, 6, 3) and at right angle to OP, where O is origin is

A. 2x + 6y + 3z + 49 = 0

B. 2x + 6y + 3z = 49

C. 2x + 6y + 3z = 47

D. 2x + 6y + 3z + 47 = 0

E. None of the above

View Answer

Correct choice: B

Explanation:

d.r. of normal to the plane
2 – 0, 6 – 0, 3– 0 = 2, 6, 3
Its equation is 2(x – 2) + 6(y – 6) + 3(z – 3) = 0
or 2x + 6y + 3z = 49
