Answer 1

A non-contact force acts on an object without physical touch. Among the given options, none of them clearly demonstrates a non-contact force, as all involve a direct interaction with a physical object. However, if we were to consider a situation involving gravity (which is a non-contact force), that would fit the definition.

If we had an option like "a book falling from a shelf," that would represent a non-contact force acting on the object due to gravity. In the provided list, all actions entail contact forces.
