Which of the following vector is equally inclined with the coordinate axes?
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
We know that a vector is equally inclined with the coordinate axes if its direction cosines are equal. Now, let a→=4i^+4j^+4k^ The direction ratios are a=4, b=4, c=4 And a→=42+42+42=43 The direction cosines of a→ are…
