Find the ratio of the electric and gravitational forces between two protons.

The ratio of electric and gravitational force between two protons.Charge of each proton is 1.6times10^(-19)C mass is 1.67times10^(-27)Kg and G= 6.67times10^(-11)Nm^(2)Kg^(-2) .

The gravitational force between two bodies is

(a) Two protons are placed at some separation in vacuum. Find the ratio of electric and gravitational force acting between them. (b) Two point charges are placed at separation 3 m in vacuum. What can be the minimum force between them. (c ) A charge Q is to be divided on two objects. What should be the value of the charges in the objects so that the force between them is maximum ? (d) Two insulating small spheres are rubbed against each other and placed 1.6 cm apart. If they attract each other with a force of 0.9 N , how many electrons were transferred from one sphere to the other during rubbing ?

Gravitational force between two bodies exist

Calculate the ratio of the electrostatic of gravitational inteaction forces between two electrons, between two protons. At what values of the specific cahreg q//m of a praticle would these forces become equal (in their absoule values) in the case of interaction of indentical) particles ?

The mass of an electron is 9.11 x 10^-31 kg, that of a proton is 1.67 x 10^-27 kg. Find the ratio F_e// F_g of the electric force and the gravitational force exerted by the proton on the electron.-

Find the ratio of the magnitude of the electric force to the grativational force acting between two protons.

What is the ratio of electric and magnetic forces between two moving charges?

The nucleus in an iron atom has a radius of about 4.0xx10^(-15) m and contains 26 protons. What is the magnitude of the gravitational force between those same two protons?
