Answer:
The correct answer will be "[tex]-\frac{6C_{6}}{x^{7}}[/tex]". The further explanation is given below.
Explanation:
The potential energy will be,
⇒ [tex]U(x)= -\frac{C_{6}}{x^6}[/tex]
The expression of force will be,
⇒ [tex]F=-\frac{dU(x)}{dx}[/tex]
⇒ [tex]=-(C_{6}(-6)x^{-7})[/tex]
⇒ [tex]=-\frac{6C_{6}}{x^{7}}[/tex]
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.
