The magnets will experience
A) only magnetic force
B) only frictional force
C) magnetic and frictional forces
D) magnetic and gravitational forces
Correct Answer: D
Solution :
This question is successfully answered by the student who can recognize the various forces that act on the magnets. All objects having mass attract each other by a force known as the gravitational force. Since both magnets have mass, they attract each other by gravitational force. Like poles of a magnet repel each other, while unlike poles attract each other by a magnetic force. Since the magnets are placed on a frictionless surface, they do not experience any frictional force. Hence, the magnets will experience magnetic and gravitational forces. The correct answer is D.
