An atomic nucleus contains Z protons. It has a total charge Q =4.8 x 10-19 C.
1) Calculate Z.
Z = 3
2) What is the magnitude of the electric field at a radius a =1.35 x 10-11 m from the center of this nucleus?
E = 23.70 x 10^12 N/C
3) A single electron, charge q = -1.6 x 10-19 C and massm = 9.11 x 10-31 kg moves around the nucleus in a circular orbit atthe radius a. Calculate the orbital speed of theelectron.
v =
4) The speed of light, c is 3 X 108 meters/sec. What isthe ratio of the calculated speed for the electron to the speed oflight.
v/c =
