Question

The accompanying figure shows a frictionless channel in the shape of a segment of a circle with center at "O". The channel has been anchored to a frictionless horizontal table top. You are looking down at the table. Forces exerted by the air are negligible. A ball is shot at high speed into the channel at "p" and exits at "r."

Consider the following distinct forces:   

  1. A downward force of gravity.
  2. A force exerted by the channel pointing from q to O.
  3. A force in the direction of motion.
  4. A force pointing from O to q.

 Which of the forces is (are) acting on the ball when it is within the frictionless channel at position "q"? 

  1. 1 only
  2. 1 and 2  
  3. 1 and 3
  4. 1, 2, and 3
  5. 1, 3, and 4
The image depicts a circular arc with three points labeled P, Q, and R. The arc is part of a larger circle centered at point O, which is marked by a small dot. The positioning of these points along the arc suggests a path or movement from P to R. - **P**: This point appears at the top left of the arc, with an arrow indicating the direction of motion starting from this point. - **Q**: Located near the bottom center of the arc, this point represents the middle stage of the path. - **R**: Positioned at the lower right of the arc, this point marks the final destination in the path. Each point appears to have a small shaded circle surrounding it, which might indicate special significance or an area of interest around these points. The arrow pointing from P towards R suggests a specific direction of progression or force acting along this path.
