A non-contact force refers to a force that acts on an object without any physical contact between the two. In the situations you provided, none of them directly describe a non-contact force, as they all involve physical interaction with the objects.
However, if you are looking for a scenario involving a non-contact force, an example would be the gravitational force acting on an object when it falls, or magnetic force acting on a magnet.
Out of the four given options, none depict a non-contact force accurately. If you have to choose the closest (even though none are correctly fitting), it would still be incorrect as they all describe contact forces. Please clarify if there’s any other context or options to consider!
