Physics - Elecrostatics Question with Solution | TestHub

A positive ion $A$ and a negative ion $B$ has charges $6.67\times 10^{-19}\mathrm{C}$ and $9.6\times 10^{-10}\mathrm{C}$, and masses $19.2\times 10^{-27}\mathrm{kg}$ and $9\times 10^{-27}\mathrm{kg}$ respectively. At an instant, the ions are separated by a certain distance r. At that instant the ratio of the magnitudes of electrostatic force to gravitational force is $P\times 10^{45}$, where the value of 10$P$ is (Take $\frac{1}{4\pi {\epsilon }_0}=9\times 10^9{\mathrm{Nm}}^2{\mathrm{C}}^{-1}$ and universal gravitational constant as $6.67\times 10^{-11}{\mathrm{Nm}}^2{\mathrm{kg}}^{-2}$ ) Assume that charge may not be an integral multiple of electrons.
