In a period of 0.9 s, 5.0 1023 nitrogen molecules strike a wall of area 7.4 cm2. If the molecules move at 330 m/s and strike the wall head on in a perfectly elastic collision, find the pressure exerted on the wall. (The mass of one N2 molecule is 4.68 10-26 kg.) Pa

Good moring let me you on this question the answer the electric force  have a good day ; )

Answer(b) both involve the use of levers;

The answer is 4f======since electrostatic force is given by    we let f be the electrostatic force when  r = 1 m    if we let  denote the electrostatic force when the distance is decreased so that r = 0.5m, then    we established earlier that f = kq₁q₂. therefore    the force will now be 4f.
