Q. I. If a system contains two point charges $q_{1}$ and $q_{2}$, the total charge of the system is obtained simply by adding algebraically $q_{1}$ and $q_{2}$, e.g., $(-2$ units charge $)+(6$ units charge $)=4$ units charge.
II. ( $-2$ units charge $)+(6$ units charge $)=8$ units charge.
III. Charge has magnitude but no direction, similar to mass.
IV. Mass of a body is always positive whereas a charge can be either positive or negative.
Incorrect statement is
