ANSWER

A stone is tied with a rope and now holding it with the other end of the rope we rotates it in the air horizontally .their will be some forces like tension which will convert into centripetal force,mass of the stone etc.if their is a mass then why it does not falls down because their is no force balancing it like normal reaction as it is in air and it is not in contact so ,normal reaction doesn't balance it .then why it doesn't falls. explain it reason?
