Question

Given $\vec{A}+\vec{B}+\vec{C}+\vec{D}=\overrightarrow{0}$, which of the following statements is not correct?

Accepted Answer

$\vec{A}, \vec{B}, \vec{C}$, and $\vec{D}$ must each be a null vector

Answer

The magnitude of $(\vec{A}+\vec{C})$ equals the magnitude of $(\vec{B}+\vec{D})$

Answer

The magnitude of $\vec{A}$ can never be greater than the sum of the magnitudes of $\vec{B}, \vec{C}$, and $\vec{D}$

Answer

$(\vec{B}+\vec{C})$ must lie in the plane of $\vec{A}$ and $\vec{D}$ if $\vec{A}$ and $\vec{D}$ are not collinear and in the line of $\vec{A}$ and $\vec{D}$, if they are collinear
