Question 7 Two objects, of masses 3 and 4 kg, are hung from the ends of a stick that is 70 cm long and has marks every 10 cm, as shown above. If the mass of the stick is negligible, at which of the points indicated should a cord be attached if the stick is to remain horizontal when suspended from the cord? A B C D E 3 kg Question 8 4 kg The figures indicate forces in different situations acting on a rod lying on a frictionless horizontal tabletop, as seen from above. The lengths of the force vectors are proportional to the magnitudes of the forces. In which situation is the rod in both translational and rotational equilibrium? A. B. D. E. C.
