Potential energy is region is given by U...

Potential energy is region is given by U= `alpha/r^(10)- beta/r^5` at equilibrium. Inter molecular distance between particle is given as r= `((2alpha)/beta)^(a/b)` . Then a will be:

A

`(A/B)^(1/5)`

B

`(B/A)^(1/5)`

C

`((2A)/B)^(1/5)`

D

`(B/(2A))^(1/5)`

Text Solution

Verified by Experts

`F =-(du)/(dr) = 0`
`rArr -10^(-11)A + 5r^(6)B = 0`
`rArr r = [(2A)/B]^(1/5)`
