A non-contact force is a force that acts on an object without physical contact. Among the given options, none of them explicitly describe a non-contact force such as gravity, magnetic force, or electrostatic force. However, if one had to choose from the options listed, none would fit the definition of a non-contact force.
In real-world scenarios, a non-contact force could be represented by the gravitational force acting on the apple when it's cut or by magnets affecting objects without touching them, but those scenarios are not mentioned in your options. Therefore, none of the provided situations describe a non-contact force acting on an object.
