The distance between two protons to generate 950N of force is 0.49 X 10⁻¹⁵ m
<u>Explanation:</u>
Given:
Mass of man, m = 100 kg
Force between man and earth = 980 N
Charge of proton, q = 1.6 X 10⁻¹⁹C
Same force is generated between them
Distance between two protons, r = ?
According to Coulomb's law:
where,
k is Coulomb's constant
k = 9 X 10⁹ Nm²/C²
According to the question:
Solving the equation:
Therefore, the distance between two protons to generate 950N of force is 0.49 X 10⁻¹⁵ m
