Magnitude of Vector Expression
View
When vector $\vec { A } = 2 \hat { i } + 3 \hat { j } + 2 \widehat { k }$ is subtracted from vector $\vec { B }$, it gives a vector equal to $2 \hat { j }$. Then the magnitude of vector $\vec { B }$ will be:
(1) $\sqrt { 5 }$
(2) 3
(3) $\sqrt { 6 }$
(4) $\sqrt { 33 }$
