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 r between sun and planet. That means 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

Kepler's third law states that square of period revolution (T) of a planet around the sun is proportional to third power of average distance i between sun and planet i.e. T^(2)=Kr^(3) here K is constant if the mass of sun and planet are M and m respectively then as per Newton's law of gravitational the force of alteaction 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 for gravitational force between two stationary point masses, both have inverse-square dependence on the distance between the charges and masses respectively, (a) Compare the strength of these forces by determining the ratio of their magnitudes (i) for an electron and a proton and (ii) for two protons. (b) Estimate the accelerations of electron an proton due to the electrical force of the mutual attraction when they are =10^(-10)m apart? (m_(p) = 1.67 xx 10^(-27) kg, m_(e) = 9.11 xx 10^(-31) kg)
