Grade 12
Question:
<p>The position vectors of the points A, B and C are <strong>i</strong> + 2<strong>j</strong> - <strong>k</strong>, <strong>i</strong> + <strong>j</strong> + <strong>k</strong>, and <strong>i</strong> + 3<strong>j</strong> + 2<strong>k</strong>, respectively. If A is [incomplete question]</p>
<p>(a) [Option incomplete in source]</p>
<p>(b) -2<strong>i</strong> + 4<strong>j</strong> - 2<strong>k</strong></p>
<p>(c) 2</p>
<p>(d) None of these</p>
Step-by-Step Solution
Key Concept: Position vectors are used to locate points in space; operations on them relate geometric points.
