Question

Help me Please..

The Force of interaction between two atoms in a certain diatomic molecules can be requested by F=-frac{a}{r^2} + frac{b}{r^3}, in w/c a and b are positive constants and r is the separation distance between the atom

Answer 1

a. Show that the separation at equilibrium is b/a
b. show that for small oscillation about this equilibrium separation the force constant is \[\frac{a^4}{b^4}\]
c. find the period of this motion.

Answer 2

@experimentX can help you with this ,sry i have to leave

Answer 3

a. is pretty trivial... you got a.?

Answer 4

yes i got it. but i need some explanation please.

Answer 5

for a.?

Answer 6

for all. please?

Answer 7

for a. F=0, find r.

Answer 8

how about b. :)

Answer 9

I'm looking at b. now...

Answer 10

you sure that's the correct value they* give in the problem?
a^4/b^4?

Answer 11

i'm not sure. i think its -a^4/b/^3

Answer 12

...

Answer 13

-a^4/b^3

Answer 14

it's +/- a^4/b^3 .... is it semi-legible or something in your book?

Answer 15

I spent 5 minutes trying to figure out how they could've gotten a^4/b^4, so it saves time if you post the right info. at the start.

Answer 16

yes it could be +/-

Answer 17

i'm sorry. :|
