Question

if we dig the hole from one end of the earth to another end and jump in it then shall we stop at center,why​

Answer 1

Answer:

With such immense speed, you completely overshoot earth's center. As you travel through the far end of the hole, gravity is now in the opposite direction and slows you down. You are slowed down to zero speed just as you emerge from the hole on the other side of the world.
