Hi,
it is well know that the force on a mass point outside to an homogeneous sphere is as the whole sphere's mass is concentred on its centre.
It seems that the reaction of this force (the total force of the point on the shepre) is applied on the centre of the sphere but, is it true?
If this is it true why tides?
Do you know a book where this is demonstrated?
thank you and excuse my english
