Vedclass · Accepted Answer

If the resultant of three non-zero vectors is zero,then the vectors must be coplanar.

Vedclass · Answer

(C) For three vectors to have a resultant of zero,they must form a closed triangle. $A$ triangle is a planar figure,so the vectors must be coplanar. This makes statement $(C)$ correct.Statement $(A)$ is incorrect because three vectors of different magnitudes can also sum to zero (e.g.,sides of a $3-4-5$ triangle).Statement $(B)$ is incorrect because four non-zero forces can sum to zero in three dimensions (e.g.,the four vectors pointing from the center of a regular tetrahedron to its vertices).Therefore,only statement $(C)$ is correct.

Which of the following statement$(s)$ is/are correct?
