A difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force. Please mark me as a brainiest!!!

Answer:
C
Explanation:
elements are classified as covalent, ionic, metallic
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
