Question
2 kg stone at the end of a string 1m long is whirled in a vertical circle at a constant speed. The speed of the stone is 4 m /sec. The tension in the string will be 52 N when the stone is-
- at the top of the circle
- at the bottom of the circle
- half way down
- none of the above
The correct answer is: at the bottom of the circle
