A physics student in a hot air balloon ascends vertically at a constant speed. Consider the following four forces that arise in this situation: F1=the weight of the hot air balloon, F2= the weight of the student, F3= the force of the student pulling on the earth, F4= the force of the hot air balloon pulling on the student. Which of the following relationships concerning the forces of their magnitudes is true?A)F4>42B)F2=-F4C)F1<F2D)F4>F1E)F3=-F4
