Based on the given information, we can conclude that the net force on Julie is zero N. This is because the upward force (labeled as F_N) is equal in magnitude to the downward force due to gravity (labeled as F_g), and they act in opposite directions. Mathematically, we can express this as:
Net force = F_N - F_g = 265 N - (-265 N) = 530 N
Since the net force is equal to 530 N in the upward direction and there are no other forces acting on Julie in the horizontal direction, she will remain in a state of rest or uniform motion (i.e., swinging back and forth at a constant speed).
This is an example of balanced forces, where the forces acting on an object are equal in magnitude and opposite in direction, resulting in a net force of zero N and no acceleration of the object.
