Number of unit vectors of the form where is
- A
- B
- C
- D
Answer & Solution
Correct Answer
(C)
Step-by-step Solution
Detailed explanation
If ai^+bj^+ck^ is an unit vector, then a2+b2+c2=1 ⇒a2+b2+c2=1 If a, b, c∈W, then possible values of a,b,c are 1,0,0, 0,1,0, 0,0,1 ∴ Three unit vectors in the form of ai^+bj^+ck^, where a, b, c∈W
