The electric force between these two electrons will be 2.8 ×10⁻¹⁹ C. The concept of electric force is used in the given problem.
Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.
The given data in the problem is;
F is the electric force
K is the Coulomb constant = 9 × 10⁹ Nm²C²
q is the elemental charge = 1.6×10^⁻¹⁹ C
The electric force is found as;
[tex]\rm F=K\frac{Q_1Q_2}{r^2} \\\\ \rm F=9 \times 10^9 \frac{(1.6 \times 10^{-9} \times 1.6 \times 10^{-9}}{((2.82 \times 10^{-15}^2} ) \\\\ \rm F=2.8 \times 10^{-9}\ N[/tex]
Hence the electric force between these two electrons will be 2.8 ×10⁻¹⁹ C.
