Answer 1

Hello!

what is the net force on this object?

A) 0 Newtons  

B) 200 Newtons  

C) 400 Newtons  

D) 600 Newtons

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.

$F_{Net} = F_{grav} - F_{air}$

$F_{Net} = 600 - 400$

$\boxed{\boxed{F_{Net} = 200N}}\end{array}}\qquad\checkmark$

Answer:

B) 200 Newtons
