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.

An insulated 40 ft^3 rigid tank contains air at 50 psia and 120°f. a valve connected to the tank is now opened, and air is allowed to escape until the pressure inside drops to 25 psia. the air temperature during this process is kept constant by an electric resistance heater placed in the tank. determine the electrical work done during this process.
