Three boxes are pushed across a frictionless horizontal surface as shown. When we compare the normal force N_2,5 that mass 2m exerts on mass 5m with the normal force N_5,10 that mass 5m exerts on mass 10m, we find that A) N_2,5 = N_5,10 = F. B) N_2,5 = F N_5,10. C) F N_2,5 = N_5,10. D) F N_2,5 N_5,10. E) F N_5,10 N_2,5.
