Question

Find a vector normal to a plane consisting of points p1(0,1,0), p2(1,0,1) and p3(0,0,1) (a) –j – k (b) –i – j (c) –i – k (d) –i – j – k The question was posed to me by my college director while I was bunking the class.

Answer 1

Correct answer is (a) –j – k The explanation is: Distance vector from p1 and p2 is a = i – j + k. Distance vector from p1 and p3 is b = –j + k. The vector normal to these points is a X b = -j – k.
