Answer:
The net force on the object is 35 N directed up.
Explanation:
Net Force
The force is a vector because it has magnitude and direction. The net force is the sum of all the individual forces acting on an object.
Let's assume the forces directed upward are positive and the forces directed down are negative.
Force A: +50 N
Force B: -30 N
Force C: +25 N
Force D: -10 N
Net Force= 50 - 30 + 25 - 10 = 35 N
The net force on the object is 35 N directed up.
