This is not as hard to calculate as you might think. Every body has an "escape velocity" which depends on the gravitational acceleration value of the body and the radius from the center BUT NOTHING ELSE. See: http://en.wikipedia.org/wiki/Escape_velocity Escape Velocity: Ve=square root of (2rg) r=radius from center, g=acceleration of gravity for the body. Set Ve=c. Solve for g. Note you will have to give r some non-zero value. Otherwise you are asking about the center of a black hole. Physics is not up to it.

What else can I help you with?
What are light independent and dependent reactions?
Light dependent reactions are reactions the capture light energy and convert it into chemical energy(ATP). It occur in the chloroplast of plant cells Light independent reactions are reactions capture energy and use it to produce food . It does not need sunlight
Do cold water fish need light?
Unless they are blind cave fish, which have no eyes, fish need light. You want a light om an aquarium so you can see the fish to best advantage. It does not need to be a special aquarium light, if a room is light enough for you to move around in, it is light enough for the fish, regardless of temperature. A weird thing may happen if the light comes from the side. Fish orientate themselves to light more than gravity. With strong side lighting they will swim tilted, sometimes almost completely on there sides.
Where do you need the specific gravity of cement?
When you need to know the total weight of of a wall, like when you want to know how strong the foundation of a building must be.
Is tire fitting light work?
No. You'll need a strong back.
Do apples need light?
yes they do, they need lots of sun and water to turn into a big strong apple
Why would a bridge builder need a strong backrgound in science?
it depends onthe science of gravity and stablization so the bridge can stand.
Why is it important for racing bikes to be both strong and light weight?
They need to be strong so that they don't break, and light so that they don't steal any more energy from the rider than they have to.
How fast does something need to be to escape the gravity of a black hole?
In order to escape the gravity of a black hole, an object would have to travel faster than the speed of light - something that is impossible.
Why does rocket taking off from the earth needs much more fuel than the same rocket taking off from the moon?
dunno and it need answer gravity is very strong on earth as the rocket gets higher gravity gets weaker they have to overpower gravity to lift of
Can you grow faster in space because earth has gravity and the gravity pulls down your spinal cord so you grow slower?
Gravity causes people to need strong bones to support their weight. Strong bones spend time adding calcium to their structure, and less time growing longer. It an environment with less gravity, bones will grow longer and not be as strong - unless they are exercised. Future space exploration must include facilities which promote healthy bone development, especially in the young.
Could you produce gravity on mars?
You don't need to produce it. There's plenty of gravity on Mars now. On the surface, it's a little more than 1/3 as strong as it is on Earth, or almost double what it is on the moon.
Do cameras require light to function?
Photography is made up of two words meaning light writing/drawing and a camera does need light to capture an image but a camera will still work/function in the absence of light: just no picture to show for it.
