charge on proton = + 1.6 × 10⁻¹⁹ C
charge on electron = -1.6 × 10⁻¹⁹ C
means magnitude of charge on electron = magnitude of charge on proton
A/C to question,
Electrostatic force between protons = F
use Coulombs law,
F = K( 1.6 × 10⁻¹⁹)(1.6 × 10⁻¹⁹)/r²
F = K(1.6 × 10⁻¹⁹)²/r²
Now, electrostatic force between two electrons when they are separated r distance from each other .
F' = K(-1.6 × 10⁻¹⁹)(-1.6 × 10⁻¹⁹)²/r²
F' = K(1.6 × 10⁻¹⁹)²/r²
Hence, F = F'
So, force act between two electrons are same e.g., F
