What am I doing wrong in this problem? Please explain to me what I am doing wrong. Thanks(adsbygoogle = window.adsbygoogle || []).push({});

h-bar is plank's constant.

E = (l(l+1)(h-bar^2))/2I (l = 1)

I = Mh*R^2 Mh = 1.67x10^(-24)g R = 161x10^(-10) cm

For I i got 4.33x10^-40

So when i plugged in I for the top equation, i got E = (1(1+1)(1.11x10^(-68)))/8.66x10^-40

which equaled to : 2.56351... x 10^-29

But I found out from a friend that E actually equals to -2.18x10^(-18) Joules

What am I doing wrong?
