You can do that with hooks:

  • Add a hook modifier to the curve.
  • Assign the “Object” in the modifier to your sphere.
  • Select curve and go into edit mode. The hook modifier will show additional buttons now.
  • Select the curve vertex at the end and click “Assign”. If you would go out of edit mode and move the sphere, the end of curve will follow, but with the original offset, which is likely unwanted.
  • So, stay in edit mode of curve, and click the “Recenter” button. Now, the end point of curve will jump to object center of the sphere, and they are connected, and moving sphere will pull the endpoint of the curve as well.

Edit:
Curve and spheres won’t appear with a unified surface though, it will look like objects sticked into each other. If you don’t want that, only solution I know is converting the curve to mesh and then use boolean maybe. So, something to do in the end, and not possible during animation.
