An object is at the top of a smooth sphere which is kept fixed. As the object slides down after being given a negligible side push,what is the behavior of the magnitude of the acceleration of the object during its motion until it reaches the ground?

  • A
    Increases and then decreases
  • B
    Decreases then becomes constant
  • C
    Increases and then becomes constant
  • D
