Before answering this question, you must know the concept between extensive and intensive property. The extensive property does not depend on the amount of substance (like mass), which is the opposite of intensive properties. From the given choices, the rest are extensive properties except for <em>amount of matter</em>. Hence, that is the answer.
Answer:
(D) F/2
Explanation:
Since the circular section is unbanked, the centripedal acceleration acting on each of the cars is


Therefore the centripetal force on each car


Since
this means the friction force required to keep the large car on the road is only half of the friction force required to keep the small car on road
So (D) F/2 is the correct answer
