A molecule of hydrogen contains two protons and two electrons. The nuclear force between these two protons is always neglected while discussing the behaviour of a hydrogen molecule. Why?

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

Calculate the ratio of electric to gravitational force between two electrons.

The force of repulsion between two electrons at a certain distance is F. The force between two protons separated by the same distance is (m_p= 1836 m_e)

The molecules contains more than two atoms are called ________ molecule.

A hydrogen atom contains one proton and one electron. It may be assumed that the electron revolves in a circle of radius 0.53 angstrom (1 angstrom = 10^(-10) m and is abbreviated as A) with the proton at the centre. The hydrogen atom is said to be in the ground state in this case. Find the magnitude of the electric force between the proton and the electron of a hydrogen atom in its ground state.

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

Assertion : Hydrogen is the simplest atom Reason : Its nucleus contains only two protons
