a hydrogen atom moving at speed `upsilon` collides with another hydrogen atom kept at rest .Find the minimum value of u for which one of the atoms may get ionized the mass of a hydrogen atom `= 1.67 xx 10^(-27)kg`

Mass of one hydrogen atom

The mass of 1 atom of hydrogen is

A H-atom moving with speed v makes a head on collision with a H-atom in rest. Both atoms are in ground state. Find the minimum value of velocity v for which one of atom may excite.

A hydrogen atom moving at a speed v absorbs a photon of wavelength 122 nm and stops. Find the value of v. Mass of a hydrogen atom = 1.67 xx 10^-27kg .

A hydrogen atom moving at a speed v absorbs a photon of wavelength 122 nm and stops. Find the value of v. Mass of a hydrogen atom = 1.67 xx 10^-27kg .

GAM of Hydrogen is 1g: Find the mass of 1 atom of hydrogen.

A neutron moving with a speed u strikes a hydrogen atom in ground state in ground toward it with the same speed Find the minimum speed of the neutron for which ineleastic (completely or perially) collision may take place .The mass of neutron = mass of hydrogen = 1.67 xx 10^(-27)kg
