|λ A |=λ| A |, if

Question

|λ A |=λ| A |, if (A) λ>0 (B) λ<0 (C) λ=0 (D) λ ≠ 0

Tardigrade Admin · Accepted Answer

|λ A |=λ| A |, if λ>0, as multiplication of vector A with a positive number λ gives a vector whose magnitude is changed by the factor λ but the direction is same as that of A.

Q. $∣ λ A ∣ = λ ∣ A ∣$ , if

$λ > 0$

$λ < 0$

$λ = 0$

$λ \neq = 0$

$∣ λ A ∣ = λ ∣ A ∣$ , if $λ > 0$ , as multiplication of vector A with a positive number $λ$ gives a vector whose magnitude is changed by the factor $λ$ but the direction is same as that of $A$ .

Q. ∣λA∣=λ∣A∣, if

λ>0

λ<0

λ=0

λ=0
