Consider the helium ion: 4, 2 He+, which has two protons and two neutrons in its nucleus.
a. What are the two main differences in the description of the motion of the electron in this ion compared to that in in H-atom.
b. Write down the normalized first excited state wave function u_210 for this ion. Define your symbols very clearly. No derivation is needed.
c. Show explicitly that the function u_210 in (b) is indeed an eigenfunction of the angular momentum square operator L^2 with eigenvalue for the angular momentum equal to h*2^1/2.
In the two-slit experiment, the distance between the slits and the screen is 1.1 m and the distance between the slits is 0.040 mm. what is the distance between the adjacent bright fringes
An electric field greater than about 3x10^6 V/m causes air to break down (electrons are removed from the atoms and then recombine, emitting light). Estimate the voltage between your finger and the doorknob
A point charge with charge q1 is held stationary at the origin. A second point charge with charge q2 moves from the point (x1, 0) to the point (x2,y2). Please use k for Coulomb's constant rather than writing it out as (1/4π?0).

A model of a red blood cell portrays the cell as a sphericalcapacitor, a positively charged liquid sphere of surface areaA separated from the surrounding negatively charged fluidby a membrane of thickness t.
If 2.63 × 1020 electrons flow through a cross section of a 3.04 millimeter diameter Copper wire in 9.28 second, and then determine what the drift speed of the electrons
Light intensity of a 100 W bulb at a certain distance is 1 W/m2. The distance is doubled. What are the electric field amplitude and the magnetic field amplitude at that new distance
A simple pendulum of length 0.8 m swings such that the pendulum reaches the maximum speed in the positive direction at a time of 0.3 seconds. At 0.4 seconds, the pendulum is at an angle of 0.05 radians. Assuming a solution of the form theta (t) = A c..
