To determine the net force acting on the object, we need to sum all the forces acting on it. For forces in the same direction, we add them together. For forces in opposite directions, we subtract the smaller force from the larger force.
In this case, we have four forces acting on the object: two pushing to the right and two pushing to the left. Let's calculate the net force by summing or subtracting these forces.
Force 1: 200N (pushing to the right)
Force 2: -500N (pushing to the left)
Force 3: 100N (pushing to the right)
Force 4: -50N (pushing to the left)
Now, let's add or subtract these forces:
200N + (-500N) + 100N + (-50N) = -250N
The sum of all the forces is -250N. Therefore, the net force acting on the object is -250N.
So, the correct answer is C. -250N.
