Optical Spectroscopy and Atomic Structure

AI Thread Summary
The discussion focuses on calculating the energy and radius of the lowest electron orbits in a Helium atom with one electron. The formula provided for the ground state energy, E0 = k(Ze)²/2r, is central to the calculations. A participant is struggling to apply this formula correctly to determine the ground energy of Helium. Assistance is requested to identify errors in their calculations. The conversation emphasizes the need for accurate application of the given equations to solve the problem.

Homework Statement



Calculate the energy and radius for each of the five lowest (n = 1,2,3,4,5) electron orbits in a Helium atom with only one electron. Enter the energy as a positive value in units of "eV" and the radius in units of "nm". Hint: The Helium nucleus has 2 protons so Z = 2 and the ground state energy of Helium will be E0 = k(Ze)2/2r.

If n=2, find E and r1

Homework Equations





The Attempt at a Solution



I know how to answer the question, but I need help with finding the ground Energy E0 of Helium. I keep ending up with incorrect answers using that equation given in the problem, can anyone help me solve for the ground energy of Helium?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
