Zero Vector

Q.

$100$ Coplanar forces each equal to $10N$ act on a body. Each force makes an angle $\raisebox{1ex}{$\pi $}\!\left/ \!\raisebox{-1ex}{$50$}\right.$ with the preceding force. What is the resultant of the forces?$?$

1. $1000N$

2. $500N$

3. $250N$

4. Zero

Q. Zero vector can be considered as a scalar because its magnitude is zero and direction is not defined.
