Assuming it to be in an earthly atmosphere ( That is if the earth is in another object of gravity equal to that of Earth), You would Require about 5.7x10^25 newtons.

Taking the question as a hypothetical one in which you want to move a mass equivalent to earth's by one cm: that depends on how fast you want it to reach that distance. From Newton's laws, F = m*a, where a is acceleration. So if you could ask the question in the following manner,
"How much force (of constant amount) does it require to move the earth 1 cm in 100 seconds?" That can be calculated. The acceleration a will be F/M (constant), and the distance moved is s = .5*a*t^2. From these formulas you can calculate F (look up M).

Sometimes powerful earthquakes affect the Earth's position. It was estimated that the December 26/04 earthquake that caused the devastating tsunami in the Indian Ocean kicked the Earth off it's axis a little bit!
If you're planning something globally devastating ... could you please let us know ahead of time?

that depends on the direction you want to push it. The earth is already moving. It will require a different force depending on what direction you would like to move it.

Too many unknowns - what are you moving it from? What is the gravitational force of the object you are moving it from?
Archimedes is supposed to have said, "Give me a place to stand and I will move the world." but he said it in Greek - something like "Dos toy sto, kai kosmon kineso."
If you have nothing to push against, you can't move it at all.

Nothing..... bcoz there is nothing underneath supporting the earth. Its floating on its place just like the rest of the other planets

Actually, all you have to do is wait a fraction of a second and it will have moved that far. Rather better to ask what it would take to slow it down 1 cm/sec with a giant rocket or push it to one side by 0.0000000001 radians from its path.
