Derive Newton's law of gravitation from Kepler's law.

Write down Newton's law of gravitation.

Kepler's third law states that square of period of revolution (T) of a planet around the sun , is proportional to third power of average distance between sun and planet ? i.e., T^2=Kr^3 here K is constant. If the masses of sun and planet are M and m respectively, then as per Newton's law of gravitation, force of attraction between them is F=(GMm)/(r^2) here G is gravitational constant The relation between G and K is described as

Coulomb’s law for electrostatic force between two point charges and Newton’s Law of gravitational force between masses depends on the distance between the charges/ masses. (b) Estimate the accelerations of electron and proton due to the electrical force of their mutual attraction when they are 1overset@A(=10^(-10)m) apart? (m_p=1.67x10^(-27)kg,m_e=9.11x10^(-31)kg)

Coulomb’s law for electrostatic force between two point charges and Newton’s Jaw of gravitational force between dependence on the distance between the charges/ masses. Compare the strength of these forces by determining the ratio of their magnitudes : for an electron and a proton and
