MCQ

The matrix $\text{A}=\begin{bmatrix}0&\text{amp};0&\text{amp};0\\0&\text{amp};4&\text{amp};0\\4&\text{amp};0&\text{amp};0\end{bmatrix}$ is $a$ :

✓
Square matrix
B
Diagonal matrix
C
Unit matrix
D
None of these

✓

Answer

Correct option: A.

Square matrix

Given, $\text{A}=\begin{bmatrix}0&\text{amp};0&\text{amp};4\\0&\text{amp};4&\text{amp};0\\4&\text{amp};0&\text{amp};0\end{bmatrix}$
The matrix is a square as it has same no. of rows and columns,
But it is not a diagonal matrix as there are elements other than diagonal ones which are not zero.
