Verify the statement that gravitational forces between two charges can be neglected compared to the electrostatic forces using the example of two electrons separated by a distance of 1m. Compare the magnitude of the Coulomb’s force and the gravitational force on each electron.
Use: Mass of an electron is 9.1×10^−31 kg.
Gravitational constant G=6.67×10^−11 Nm^2/kg^2.
Coulomb's constant k=9×10^9 Nm^2/C^2.
Charge of an electron is −1.6×10^−19 C.
