Question

What is the net force of this object? A. 400 newtons B. 200 newtons C. 0 newtons D. 600 newtons @Dexteright02

Answer 1

In this case, as the meanings of the vectors are opposite, one of the forces receives the negative signal and thus a piece of the other vector is drawn, as shown in the figure. And to know the module of the resultant force, if it subtracts the modules of the forces.

$F_{Net} = F_{grav} - F_{air}$
$F_{Net} = 600 - 400$
$\boxed{F_{Net} = 200N}$
Answer:
B. 200N
