Answer:
<u>The girl should leave the string a time when the ball is at a position tangent at that point of the circle passes through the location of target.</u>
Explanation:
The direction of an object moving in circular path changes endlessly with time. The direction of the object at some extent are within the direction of tangential drawn to the circle at that point,
The centripetal force on the ball becomes zero once the girl leaves the string. hence, the ball can go into the direction tangential to the circle at the point whenever she left the string.
