If A is skew symmetric , then kA is a …….

If A is skew symmetric then kA is a ……. (k is any scalar)

If A is skew symmetric matrix, then I - A is (where I is identity matrix of the order equal to that of A)

If A is skew symmetric matrix, then I - A is (where I is identity matrix of the order equal to that of A)

If A and B are square matrices of the same order, then (i) (AB)=......... (ii) (KA)=.......... (where, k is any scalar) (iii) [k(A-B)]=......

If A and B are square matrices of the same order, then (i) (AB)=......... (ii) (KA)=.......... (where, k is any scalar) (iii) [k(A-B)]=......

State'True'or'false':If A is any skew symmetric matrix, then A^2 is also skew symmetric.

If a matrix A is both symmetric and skew-symmetric, then A is a diagonal matrix (b) A is a zero matrix (c) A is a scalar matrix (d) A is a square matrix
