Explanation / Answer

Given    weight of the package onmoon   Wm       mgm = 31 N        we know that                  gm = g e   /6       weight of the package on earth   We    = m ge                                                                = 6 Wm     = 6*31 = 186N    mass of package onmoon     m = 31*6 /9.8                                                         = 18.97 kg mass of package on earth     m =186 / 9.8 = 18.97 kg               Forcesacting on opposite direction              netforce    = 5 - 8 =3 N        Forces acting on   same direction = 8 + 5 = 13N
