A ball on a string moves in a vertical circle as shown in (Figure 1). Figure1 of 1 A ball on a string moving counterclockwise in a vertical circle is shown. Part A Choose the correct free-body diagram for the case when the ball is at its lowest point. A free-body diagram of a ball on a string moving counterclockwise in a vertical circle is shown. The ball is at its lowest point. The vector labeled as T is directed vertically upwards. The vector labeled as w is directed vertically downwards. The vectors have equal magnitudes. A free-body diagram of a ball on a string moving counterclockwise in a vertical circle is shown. The ball is at its lowest point. The vector labeled as T is directed vertically upwards. The vector labeled as w is directed vertically downwards and has the magnitude greater than the magnitude of the vector T. A free-body diagram of a ball on a string moving counterclockwise in a vertical circle is shown. The ball is at its lowest point. The vector labeled as T is directed upwards and to the left. The vector labeled as w is pointed at the opposite direction. The vectors have
