Question

a stone is tied to a string and whirled around in a circle at a constant speed. is the string more likely to break when the circle is horizontal or when it is vertical?

Answer 1

The string is more likely to break when the circle is vertical

Step-by-step explanation:

The string is more likely to break when the circle is vertical because tension in the string is the same throughout the circular motion and it is equal to mrw^2 when it is rotated in the horizontal plane while tension in the string is maximum and is given by mrw^2+mg when in the vertical plane.
