Consider:
g = -GM / ( r^2 - e^2 )
where
g is the acceleration,
G is the gravity constant,
M is the mass of the black hole,
r is the distance from the black hole's center,
e is the radius of the event horizon.
From Wikipedia: "Attempting to make an object near the horizon remain stationary with respect to an observer requires applying a force whose magnitude increases unbounded (becoming infinite) the closer it gets." http://en.wikipedia.org/wiki/Event_horizon#Interacting_with_an_event_horizon
