An engineering student has made a robot mouse that is running around a circle on a horizontal table. The mouse is kept on its circular path by a string that is attached to it and passes through a hole in the center of the table. The student, below the table pulls on the string with a tension 16.00 N to keep the mouse on a circular path of a particular radius.
