Write down Newton's law of gravitation.

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

Write down Mendel's Law of Segregation. Mention one difference in between phenotype and genotype.

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 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

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)
