Maximum electric field of a circular ring
If you ignore the coefficients, your function will be
$$f(x) = \frac x{\left(x^2 + r^2\right)^{3/2}}.$$
Differentiating w.r.t $x$ gives you
$$\begin{align}
\text{simple product rule}\ f(x) &= u(x)\ti …

Unification of Newtonian gravity and electrostatic force
A dipole has two parameters magnitude and orientation. If you change the orientation the nature of the force also changes (i.e from attractive to repulsive), so what you are saying is if you drop a bo …
