Question

Figure shown of a molecule of Ammonia, NH3. Each bond length- the distance betweenthe nitrogen atom and each hydrogen atom is 1.22*10^-10m. The mass of H and N    mH= 1.67*10^-27 kg    mN= 23.3*10^-27 kg Find the moment of inertia of this molecule about the x axisshown in the figure. Treat all of the atoms as point masses. The mass of H and N    mH= 1.67*10^-27 kg    mN= 23.3*10^-27 kg Find the moment of inertia of this molecule about the x axisshown in the figure. Treat all of the atoms as point masses.

Explanation / Answer

the 2 atoms on the x-axis do not contribute as they are on the axisof rotation. contribution of the other 2 H atoms are MOI = 2 * 1.67 * 10-27 * (1.22 * 10-10 * cos300)2 compute this. hope this helps!
