Question 1 Report
Which of the following are contact forces? I. Force of tension II. Force of fiction, III. Magnetic force III Force of reaction.
Answer Details
Contact forces are forces that require physical contact between two objects to occur. Based on this definition, only forces of tension and friction are considered contact forces among the options given.
Force of tension is a force that is transmitted through a string, rope, or cable when it is pulled tight by forces acting from opposite ends. It is a contact force because it requires physical contact between the string or cable and the objects pulling on it.
Force of friction is a force that opposes motion between two surfaces in contact. It is a contact force because it requires physical contact between the two surfaces.
Magnetic force and force of reaction are not contact forces because they do not require physical contact between two objects to occur. Magnetic force occurs between two magnetic objects, and force of reaction is the force exerted by a surface in response to an object pressing against it.
Therefore, the correct answer is (b) I, II, and IV only.
