Question

A molecular interaction along a line is approximated by U(x)=Cx5−Dx\displaystyle U(x)=$$Cx^5$$-\frac{D}{x}, where CC  and DD  are positive constants. Determine the expression for the force.

Accepted Answer

−5Cx4−Dx2\$$displaystyle-5Cx^4$$-\frac{D}{$$x^2$$}

Answer

−5Cx4+Dx2\$$displaystyle-5Cx^4$$+\frac{D}{$$x^2$$}

Answer

−Cx5+Dx\$$displaystyle-Cx^5$$+\frac{D}{x}

Answer

5Cx4+Dx2\$$displaystyle5Cx^4$$+\frac{D}{$$x^2$$}

A molecular interaction along a line is approximated by U(x)=Cx5−Dx\(\displaystyle\) U(x)=Cx^5-\(\frac{D}{x}\), where CC and DD are positive constants. Determine the expression for the force.

A molecular interaction along a line is approximated by $U (x) = C x^{5} - \frac{D}{x}$ , where $C$ and $D$ are positive constants. Determine the expression for the force.
