Issac Newton
He explained both the gravity of the earth and the motion of the planets with the solar system, which is also due to gravity, with his well known third law of motion.

Answer:
F = 2.49 x 10⁻⁹ N
Explanation:
The electrostatic force between two charged bodies is given by Colomb's Law:
![F = \frac{kq_1q_2}{r^2}\\](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7Bkq_1q_2%7D%7Br%5E2%7D%5C%5C)
where,
F = Electrostatic Force = ?
k = colomb's constant = 9 x 10⁹ N.m²/C²
q₁ = charge on proton = 1.6 x 10⁻¹⁹ C
q₂ = second charge = 1.4 C
r = distace between charges = 0.9 m
Therefore,
![F = \frac{(9\ x\ 10^9\ N.m^2/C^2)(1.6\ x\ 10^{-19}\ C)(1.4\ C)}{(0.9\ m)^2}](https://tex.z-dn.net/?f=F%20%3D%20%5Cfrac%7B%289%5C%20x%5C%2010%5E9%5C%20N.m%5E2%2FC%5E2%29%281.6%5C%20x%5C%2010%5E%7B-19%7D%5C%20C%29%281.4%5C%20C%29%7D%7B%280.9%5C%20m%29%5E2%7D)
<u>F = 2.49 x 10⁻⁹ N</u>
