Question

the electric force between two protons is how many times the gravitational force between them for any fixed distance
​

Answer 1

Answer:

This calculation says that the electric force between two electrons is always 4.1 x 1042 times as great as the gravitational force between them at any distance!

Answer 2

Concept Introduction:-

The universal attracting force which exists among objects are referred as gravitational force.

Given Information:-

We have been given that electric force between two protons.

To Find:-

We have to find that how many times the gravitational force

Solution:-

According to the problem

Gravitational force $=\frac{\mathrm{G}\left(\mathrm{m}_{\mathrm{p}}\right)^{2}}{\mathrm{r}^{2}}$

$&\text { Electric force }=\frac{\mathrm{K}(\mathrm{e})(\mathrm{e})}{\mathrm{r}^{2}} \\&\text { Ratio }=\frac{\mathrm{K}\left(1.6 \times 10^{-19}\right)^{2}}{\mathrm{r}^{2}} \times \frac{\mathrm{r}^{2}}{\mathrm{G} \times\left(1.67 \times 10^{-27}\right)^{2}} \\&=\frac{\left(9 \times 10^{9}\right) \times\left(1.6 \times 10^{-19}\right)^{2}}{\left(6.67 \times 10^{-11}\right)\left(1.67 \times 10^{-27}\right)^{2}} \\&=1.23 \times 10^{20} \times 10^{16} \\&=1.23 \times 10^{36} \text { (order of magnitude) }$

Final Answer:-

The gravitational force between them for any fixed distance is $1.23\times 10^{36}$.
