a. Coulamb

b.,c

Coulumb's law states the ratio of the product of the charges of two particles to the distance between the particles squared is proportional to the total force of the charge exerted by both of the particles (Newton's third law holds they are equal and opposite). The constant of proportionality would be k, or the universal electrostatic constant approximately equal to 8.99?109N?m2C2.8.99?109N·m2C2. Thus, the formula is Fe=kq1q2r2Fe=kq1q2r2.

Coulumb's law is similar to Newton's Law of Universal Gravitation, which states the ratio of the product of the gravitational forces of two particles to the distance between the particles squared is proportional to the total force of the charge exerted by both of the particles (Newton's third law holds they are equal and opposite). The constant of proportionality would be G, or the universal gravitational constant approximately equal to 6.67?10?11N?m2kg2.6.67?10?11N?m2kg2. Thus, the formula is Fg=GF1F2r2Fg=GF1F2r2.

As you can see, Newton's Law of Universal Gravitation and Coulumb's law have many similarities. I believe Coulumb's law can be based on Newton's Law of Universal Gravitation.

Yes, Coulumb's law (As well as Newton's Law of Universal Gravitation) do imply Newton's third law of motion. As you can see, it was an integral part of determining that the forces exerted by the particles are equal and opposite.
