Assuming charge 1 is located at the origin of the x axis and the positive x axis points to the right, find the two possible values x3,rx3,r (the position of charge 3 to the right of charge 1) and x3,lx3,l (the position of charge 3 to the left of charge 1).

Aphoton is absorbed by an electron that is in the n = 3 state of a hydrogen atom, causing the hydrogen atom to become ionized. very far away from the nucleus, the released electron has a velocity of 750,000 m/s. what was the wavelength of the absorbed photon?
