The weight Mg of an extended body is generally shown in a diagram to act through the center of mass. Does it mean that the earth does not attract other particles? |

Answer» The earth does attract each and every particle. The resultant of all these forces of attraction is Mg which acts at the center of mass (where M is the total mass). That is why weight Mg of an extended body is generally shown in a diagram to act through the center of mass. |
