What are the similarities and differences between coulomb's force and gravitational force?

Answer 1

similarities between these 2 force are thatboth of these forces are directly proportional to the product of masses and inversely proportional to the square of distance between the two massesand the differences are that coulombsforce could be repulsive or attractive but gravitational force is only attartive one and gravitational constant is smaller than electric constant

Answer 2

(1) They both act between at least two objects; that is, one object has no gravitational force or electromagnetic force all by itself. (2) They are both inverse-square laws; that is, each gets stronger or weaker according to the squared distance between the two objects that are exerting force on each other. Fe = kq1q2/s2 and Fg = Gm1m2/s2 where s is the distance between objects. (3) They are both capable of being forces of attraction under favorable circumstances. Take your pick.

Answer 3

Electrostatic and gravitational forces are similarly real or potential forces, as opposed to vector forces. Real; forces have positive squares and vector forces have negative squares.

Answer 4

At short distances, electromagnetic force is much, much stronger than gravitational force. At long distances, gravitational force is much, much stronger than electromagnetic force.
