If A is a skew-symmetric matrix of order 5 , then \(|a d j A|\) is equal to
- A \(-1\)
- B 0
- C 5
- D \(-5\)
Answer & Solution
Correct Answer
(B) 0
Step-by-step Solution
Detailed explanation
\(|A|=0\) (for skew-symmetric matrix of odd order) \(|adj A| = |A|^{n-1}\) \(|adj A| = 0^{5-1}\) \(|adj A| = 0^4 = 0\)
