Answer :
An electron and proton are separated by a distance, and the distance is: 1.517 × 10⁻¹⁴ m.
What is the charge of electron?
Positively charged particles include electrons. The magnitude of the negative charge is 1.602 x 10⁻¹⁹ C.
The electron, the lightest known stable subatomic particle, is regarded as the fundamental representation of electric charge.
Given that,
Charge of the electron is 1.602 x 10⁻¹⁹ C
electric force between them is 1.000 N
Electrostatic force between electron and proton:
F = [K × q(p) × q(e)] / r²
or, r² = [K × q(p) × q(e)] / F
or, r² = (8.99 × 10⁹ N.m²/C²) × (1.602 × 10⁻¹⁹ C)²
or, r = 1.517 × 10⁻¹⁴ m
here. co-efficient = 1.517 and exponent = -14
