An oxygen molecule consists of two oxygen atoms, (o2), whose total mass is 5.3 × 10–26 kg and whose moment of inertia about an axis perpendicular to the line joining the two atoms, midway between them, is 1.9 × 10–46 kg • m2 . from these data, estimate the effective distance d between the atoms?

Answer : The distance between the two atoms is

Explanation :

The The formula used for moment of inertia for one atom is:

The formula used for moment of inertia for two atom is:

where,

I = moment inertia =

r = distance of atom from axis of rotation

m = mass of atom =

Now put all the given values in the above formula, we get:

Now we have to calculate the distance between the two atoms.

Formula used :

where,

d = distance between the two atoms

Therefore, the distance between the two atoms is
