In a hydrogen atom,the electron and the proton are situated at a distance of about 0.5x10-10m from each other.The mass of the proton M,is approximately 2000 times that (m) of the electron.Using Coulomb's Law and Newton's gravitational Law,find the ratio of the intensities of electric and gravitational forces reigning between the electron and the proton.The following data is provided:The charge intensity e of either proton or electron is 1.6x10-19 Coulomb.The mass m of the electron 0.9x10-30kg.The gravitational constant G is 6.7x10-11(MKS).The coefficient which is unity in the expressions of Coulomb's Law,in CGS unit System,becomes about 9x109 in MKS unit system.

In 1959 Lyttleton and Bondi suggested that the expansion of the Universe could be ex plained on the basis of Newtonian mechanics if matter carried a net electric charge. Imagine a spherical volume, V, of astronomical size containing unionized atomic hydrogen of uniform number density n- NH/V, where N is the total number of hydrogen atoms, and assume that the proton charge is qp (1 +η) q , where q is the electron charge. So, η tells us how different...
