Question

If I dig a tunnel b/w two poles of earth and then jump into it, where will I end up??? Anyone who will give a correct answer gets 100 pts. ​

Answer 1

Explanation:

according to me I believe that there could be two possible answers or theories of this question.

Answer 1 :

if you dig a hole b/w two poles and then hum into it then you will start falling towards the centre of the earth. you will keep on accelerating until you reaches the centre of the earth as you will reach there you will feel gravity acting on you from all the directions.

Due to this all the forces will cancel and the resultant force in this case would be zero.

So, now you will start floating threre.

Answer 2 :

It may confuse you after reading the above answer. But these are just theories so don't get confused because no one knows it is possible or not.

So if you jump in that hole then the same thing will happen as it was happened in the first case. You will start accelerating but in this case when you will reach in the centre of the earth instead of just floating you will experience a downward force(towards the other pole) and then again after reaching the other pole you will again move towards the other pole. And this process will keep on happening you will never came out until someone catches you .

I hope it is correct.

Answer 2

Between the two poles the core of the earth is located and it is impossible for any material to go there and it reaches there then due to heat and pressure, it will get evaporated. Though if I think so, that something has fallen there or someone has gone by ignoring the things which may occur in reality, then the object or the person will experience experience an upward-thrust and will come above. Because, at the centre of the earth the value of g  (accleretion due to gravity ) is 0 and it is moreover such a place which is neither belonged to northpole nor belonged to the southpole so, it will repulse every object.

But, the upward-thrust is not so strong that will reach you upto the pole so, after coming to the certain height you will go again towards the core and the process will be continued. But if you start from the northpole then your locomotion will be from the northpole to the core and from the core to the northpole only and if you start from the southpole then your locomotion ill only be from the southpole to the core and from the core to the southpole only.

Hope, it may help you. Thanks....................................
