Question

The potential energy of a pair of hydrogen atoms separated by a large distance x is given by U(x)=−C6/x6, where C6 is a positive constant. Part A What is the force that one atom exerts on the other? Express your answer in terms of C6 and x. Fx = nothing Request Answer Part B Is this force attractive or repulsive? Is this force attractive or repulsive? attractive repulsive

Answer 1

The correct answer will be "
`-(6C_(6))/(x^(7))`". The further explanation is given below.

Step-by-step explanation:

The potential energy will be,

⇒
`U(x)= -(C_(6))/(x^6)`

The expression of force will be,

⇒
`F=-(dU(x))/(dx)`

⇒
`=-(C_(6)(-6)x^(-7))`

⇒
`=-(6C_(6))/(x^(7))`

Force seems to be appealing because the expression has been negative. It therefore means that the force or substance is acting laterally in on itself.
