if a hole is drill from north pole to south pole of the earth and if we drop a coin from the south pole were will the coin come out?
Answers
Answer:
the coin will stay forever at core because gravity works on both ploes an maybe get melted because of lava
Answer:
An object (100kg ferrous cube) enters the hole from party's surface. Gravity and electromagnetism would attract the object to the CENTER (nexus). On arrival at the center there exists no gravitational field or EM to repel (egress) the object. The spinning ferrous core would assimilate the captured object. Movement of the object would cease it's forward motion. Since the drop was powered by the forces of gravity, the center of the core would represent Earth's null state. Although the Sun and other celestial bodies would still exert gravitational pull the amount of Force required would be insufficient to allow the object to reverse polarity and eject itself from the core' s nexus.
Planetary gravity works from the center outward 360 degrees.
Once inside the planet the object would never exist under its own power. Gravity's pull is ubiquitous in all directions. The phenomena of spin on a molten iron (ferrous) core would also create a magnetic field aligned on the X|Y axis demonstrating one positive and one negative polarity. We see this as the North and South poles. The poles are aligned on the two lesser moving surface area during planetary spin. The axis that is found at the maximum diameter of the spin we call the “Equator" aka equal polarity +/- .
There are equatorial regions a magnetic compass metrics are nullified since equal pull is experienced North versus South.
It is in the above mentioned variables the presenter poses this thought experiment.
NOT mentioned here :
the Earth is spinning at approximately 1000 miles per hour (1600 km/hr).
The Earth is also moving around the Sun at 67,000 mph (107,000 km/h).
In addition our galaxy is moving as the Universe expands at 1,300,000 mph (2,100,000 km/h).
These factors are mentioned as YOUR FALLING OBJECT is approaching the core at approximately 120mph.
Better said: the object is in a triple helix spiral with dynamic movement of 120mph (x) 1000mph (x) 67,000mph (x) 1,300,000 mph all the duration being buffeted by Photon laden gravitational waves and electromagnetism.
The drop is not in a straight linear fall-- it's actually quite complex of you think about it.
One more note of caution in this thought experiment… nothing can be ‘heat proof' given the construct of the scenario. Heat is an attribute of Energy-- and the entire experiment is built upon how energy functions on a falling object.
