Step 1
Step 1: To find the minimum value of the function $U(x) = \frac{a}{x^2} - \frac{b}{x}$, we need to find the critical points by taking the first derivative and setting it to zero. Show more…

The potential energy, $U$, of a particle moving along the $x$ -axis is given by \[ U=b\left(\frac{a^{2}}{x^{2}}-\frac{a}{x}\right) \] where $a$ and $b$ are positive constants and $x>0 .$ What value of $x$ minimizes the potential energy?
