The correct answer is: A. Non-contact force
A non-contact force is a force that acts between two objects without the two objects touching each other. Examples of non-contact forces include magnetic forces, electric forces, and gravitational forces.
A muscular force is a force that is exerted by muscles. Muscular forces are contact forces because they act between two objects that are in contact with each other.
A contact force is a force that acts between two objects that are in contact with each other. Examples of contact forces include friction, normal forces, and air resistance.
An electrostatic force is a force that acts between two objects that have an electric charge. Electrostatic forces are
contact forces because they act between two objects that are in contact with each other.The force exerted by a magnet is an example of a non-contact force because it acts between two objects (the magnet and the object it is attracting or repelling) without the two objects touching each other.
