will the gravitational field created by a point of mass m be the same than that of a spherical object of same mass (outside the volume of the object)? If so, why is this? How does the sum of the grav forces created by all the points in the sphere add up to the same as a point-mass?(adsbygoogle = window.adsbygoogle || []).push({});

Thanks,

Alex
