The given ratio is
Where,
Gravitational constant
Its unit is
and Masses of electron and proton.
Their unit is
e Electric charge.
Its unit is
A constant
Permittivity of free space
Its unit is
Unit of the given ratio
Hence, the given ratio is dimensionless.
This is the ratio of electric force to the gravitational force between a proton and an electron, keeping distance between them constant.
