Hey, could someone please help me out? This is a silly problem, but I am unable to figure it out. The problem is that a 1 m diameter hole is dug from North Pole to South Pole. Then, a ball is thrown in the hole. Where will the ball go? Will it remain at the North Pole, or go to the South Pole or get stuck in between ( at the centre )? According to me, it should be the last one, the ball goes to the centre bcoz the gravitational force should be the highest there. But, then it is a hole. So, someone please help me out! Thanks.
