Gravitational Conditions: Dust Cloud vs Black Hole

I am sure to those of you who know GR this will be a simplistic question.
I can only hope there will be a simplistic and definitive answer :-)

Assume a dust cloud of radius=5 and a mass =mc
ANother equivalent mass of condenced matter md=mc
with a radius=1
What would be the relative gravitational conditions at a distance r=20 wrt each of these masses?
In general terms without the need for specific quantification.

The same question in another context.
A star collapses to a black hole; Assuming no mass loss in the collapse what would be the gereral effects outside the original precollapse radius or would there be??

Thanks

No effect. The Schwarzschild solution does not assume a particular distribution of matter, only spherical symmetry. Then it calculates the curvature in the vacuum outside that distribution of matter.

Thanks DaleSpam Couldn't have asked for a simpler or more definitve an answer.
