Question
A tennis ball attached to a rope moves in a vertical circle. While the tennis ball is at its lowest point, the tension in the rope is Equal to the gravitational force on the tennis ball. Less than the gravitational force on tennis ball. Greater than the gravitational force on tennis ball.
Solution
The tension in the rope when the tennis ball is at its lowest point is greater than the gravitational force on the tennis ball. Here's why:
-
When the tennis ball is at the lowest point of its circular path, it experiences two forces: the gravitational force pulling it downwards and the tension in the rope pulling it upwards.
-
The net force acting on the tennis ball is the centripetal force, which is responsible for keeping the ball moving in a circular path. This force always acts towards the center of the circle.
-
At the lowest point, the direction of the centripetal force is upwards. Therefore, the tension in the rope must provide not only the force to balance the gravitational force but also the force to keep the ball moving in a circle.
-
Therefore, the tension in the rope is greater than the gravitational force on the tennis ball at the lowest point.
