Two $1.0g$ spheres are charged equally and placed $2.0cm$ apart. When released, they begin to accelerate at role="math" localid="1650358356011" $150m/s^2$ . What is the magnitude of the charge on each sphere?

A mathematical object's volume, or size, is a quality that indicates whether it is larger or smaller than other objects of the same kind. The stated result of an arrangement —of the class of objects to something that relates —is an object's magnitude.

Along the line that joins their centres, the two spheres simultaneously acted upon by a stress of equal size and opposing direction. Coulomb's law determines the magnitude of this foce.

$F=k\frac{q^2}{r^2}$

with $q$denotes each structure's charge and $r$denotes the distance between their centres. Newton's second law states that the total between acceleration and force.

$F=ma$

We have

$ma=k\frac{q^2}{r^2}$

Substitute in $q$

$q=\sqrt{\frac{ma{r}^2}{k}}$

Already we have

$m=1\mathrm{g}={10}^{-3}\mathrm{kg}$

$r=2.0\mathrm{cm}=2.0\cdot {10}^{-2}\mathrm{m}$

$a=150m/s^2$

And $k=9\cdot {10}^9{\mathrm{Nm}}^2/C^2$. Incorporating this into the charge expression

$q=82nC$.
