what would happen
would it reach the other side
or would gravity pull it back and forth between both ends

oops i should check my spelling i did mean drill a hole not frill a hole lol boy do i feel clever.

I remember the discussion from my physics class. Just not the details. If you assume that the earth is a perfect sphere, the force of gravity is unchanging. No problems going through the core, and zero friction.... then If you dropped an object in the hole from 3 feet, it would come out 3 feet on the other end.
Also, If you drilled a tunnel from New York to each of the following cities, Peking. Moscow, Honolulu. London. The train would travel on frictionless tracts and be gravity propelled, which would be the longest and shortest trip by distance and by time?
The surprise answer was that it would take the same time for all locations,

It would oscillate back and forth. When you dropped it, it would (disregarding terminal velocity) continue to accellerate until it got to the center of the earth. After it passed through the center of the earth it would be slowed by the pull of gravity as it fell "up" until the forces of gravity overcame its speed and it reversed direction and fell the other way. Taking into account the laws of physics it would continue to go back and forth, not quite as far each time it came to the point where it stopped and reversed direction. It would keep this up until it stopped at the exact center of the earth.

Assuming you are neglecting resistance due to air, and heat due to the mantle and core, the object would still hit the side of the hole and crash due to the rotation of the Earth. Any other questions?

melt and if it was some sort of material that cant melt which doesnt exist it would go through the middle then gravity will pull it back and after a while it will stop in the middle

It would pull towards and stay in the middle. The center of gravity.
Given of course, that the heat doesnt either push it back up or melt it.

It will pull it back and forth and finally settledown in the middle.

It depends on a lot of things -- for my very long-winded explanation of the answer to this, look for my reply to this question:

it wouldn't stop if we did not have air friction. otherwise it would oscillate back and forth without end.

I would throw Bob's keys down there and after that I would not care.

it would melt....not too far down the hole...
