The graph shows the velocities of two objects as function of time. Mass of object-1 is twice
\( \mathrm{P} \) of that of object-2. Net forces \( F_{A}, F_{B} \), and \( F_{C} \)

W are acting on the objects during intervals \( A \), \( \mathrm{B} \), and \( \mathrm{C} \), respectively. Which one of the following choices is the correct relationship between the magnitudes of the net forces?
(1) \( \mathrm{F}_{\mathrm{B}}=\mathrm{F}_{\mathrm{C}}\mathrm{F}_{\mathrm{A}} \)
(2) \( \mathrm{F}_{\mathrm{C}}=\mathrm{F}_{\mathrm{B}}=\mathrm{F}_{\mathrm{A}} \)
(3) \( F_{A}F_{B}=F_{C} \)
(4) \( F_{A}F_{B}F_{C} \)
