What is the shortest distance between the two skew lines and ?
Answer and explanation
Correct answer: D.
.
Magnitude: .
Magnitude: .
- Step 1: Identify point vectors , , so .
- Step 2: Compute the cross product of the direction vectors and :
- Step 3: Calculate dot product: . Distance .
Answer
.
Why not the others: uses incorrect vector cross product magnitudes; is an arithmetic error; ignores directional components.
