The force of attraction, which is proportional to the mass of the particle, acts vertically downwards and is known as weight of the body.As the *distance between the different particles of a body and the centre of the earth is the same, therefore these forces may be taken to act along parallel lines. We have already discussed in Art. 4.6 that a point may be found out in a body, through which the resultant of all such parallel forces act. This point, * Strictly speaking, this distance is not the same. But it is taken to the same, because of the very small size of the body as compared to the earth.
