INTERESTING SCIENCE QUIZ

Imagine that there is a hole in the earth from South pole to North pole.I drop a ball from South pole .What will happen to the ball ???

Answer :

All objects are pulled towards the center of the earth.So the ball dropped from the South pole will gain speed and rush towards the center of the earth,when it reaches the center of the earth it gains maximum speed.It cannot stop at the center of the earth because of its speed.It will continue to travel towards North pole.Now its speed gets reduced as it is pulled back towards the of the earth.When its speed becomes zero it will reverse its direction of travel and gain maximum speed when it comes to the center of the earth.Now it will proceed in the direction of South pole and will be oscillating in a straight line.It will be traveling in both directions with the center point as the center of the earth.This explains gravitational pull and don't think there is hole from North to South pole...
