What is the name of the mutual force acting between any two bodies in the universe ?

According to Newton's law of gravitation , everybody in this universe attracts every other body with a force, which is directly proportional to the product of their masses and the inversely proportional to the square of the distance between their centres, i.e., F prop (m_1m_2)/(r^2) or F=G(m_1m_2)/(r^2) where G is universal gravitational constant =6.67xx10^(-11)N*m^2*kg^(-2) . Read the above passage and answer the following questions : (ii) How is the gravitational force between two bodies affected when distance between them is halved ?

What is the name of attractive force which act between two bodies in the universe

What will be the change in the force constant of a spring if its length is doubled?

The electrostatic force between two point charges and the gravitational attractive force between two point masses- both are inversely proportional to the square of the distance between the charges and the masses, respectively. (1)(a) Compare the eletrostatic force (F_(C)) and the gravitational force (F_(G)) between an electron and a proton. (b) Compare F_(C) and F_(G) between two protons. (ii) Find out the accelerations of an electron and of a proton due to the electrostatic force between them when htey are placed at a distance of 1 Å

What are the characteristics of an elastic collision between two bodies ?

The force of interaction between two charges placed in vacuum is F . What will be the force be the force between the charges placed at the same distance in a medium of dielectric constant K ?

Columb law for electrostatic force between two point charges and newton law for gravitational force between two 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 acceleratons of electron and proton due to the electrical force oftheir mutual attarction when they are 1A (=10^(-10) m) a part (m_(p)=1.67xx10^(27) kg m_(e )=9.11xx10^(-31) kg)

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)
