Question

a student claims that there are similarities between the magnetic force they observed and gravitational force. which statement correctly identifies a similarity that would support the students claim? a. both magnetic and gravitational forces are examples of contact forces. b. both magnetic and gravitational forces depend on the mass and distance between the objects. c. both magnetic and gravitational forces are examples of non - contact forces that act at a distance. d. both magnetic and gravitational forces involve attractive forces and repulsive forces between objects.

Explanation:

Magnetic and gravitational forces are non - contact forces that can act at a distance. Magnetic forces can be attractive or repulsive, and gravitational forces are always attractive. Both can act between objects without the objects being in direct contact. Option B correctly states that both are non - contact forces that act at a distance. Option A is incorrect because gravitational force is not a contact force. Option C is wrong as gravitational force depends on mass and distance, but magnetic force depends on magnetic properties and distance, not mass in the same way. Option D is incorrect as gravitational force is only attractive while magnetic force can be attractive or repulsive.

Answer:

B. Both magnetic and gravitational forces are examples of non - contact forces that act at a distance.
