Question

Electron (-) has a charge of 1.6 x 10-19 C. Proton (+) has a charge of 1.6 x 10-19 C. In a hydrogen atom the distance between a proton and an electron is
5.3 x 10-12 meter.
(A) Calculate the force acting between the proton and the electron. Show your work. Remember to include a correct force unit in your final answer.







(B) Why does it generally require energy (ionization energy) to remove an electron from an electron cloud? Hint: think of charges.



(C) To lift a 2lb dumbell off the floor to a height of your thigh would require about one Newton of force (1N). How many dumbells at once would you have to pick off a floor to your the height of your tight to show the magnitude of force acting between a proton and an electron?

2-lb dumbbell

Answer 1

Answer:

c because you can lift a 2 pound dumbell
