The unit vector to the points p1(0,1,0), p2(1,0,1), p3(0,0,1) is
(a) (-j – k)/1.414
(b) (-i – k)/1.414
(c) (-i – j)/1.414
(d) (-i – j – k)/1.414
The question was posed to me in an online interview.
The above asked question is from Position and Distance Vectors topic in chapter Vector Analysis and Applications of Electromagnetic Theory
