Answer:
Explanation:
charge, q = 1.6 x 10^-19 C
distance, r = 911 nm = 911 x 10^-9 m
The Coulomb's force is given by


F = 2.78 x 10^-16 N
The force between the electron and the proton is 2.78 x 10^-16 N.
Have everything in control and in order and discuss about different issues.
Uncertainty means that your result may be very random, so you can't trust the first or second or so observation, making several samples critical for accuracy. <span />
