When vector A→=2i^+3j^+2k^ is subtracted from vector B→, it gives a vector equal to -2j^. Then the magnitude of vector B→will be :

B→−A→=−2j^⇒B→=A→−2j^=2i^+1j^+2k^ |B→|=22+12+22=3

Detailed Solution

$\vec{B} - \vec{A} = - 2 \hat{j} \Rightarrow \vec{B} = \vec{A} - 2 \hat{j} = 2 \hat{i} + 1 \hat{j} + 2 \hat{k} | \vec{B} | = \sqrt{2^{2} + 1^{2} + 2^{2}} = 3$
