1. For hydrogen atoms in a d state, sketch the orbital angular momentum with respect to the z axis. Use units of U along the z axis and calculate the allowed angles of L with respect to the z axis.
2. For a hydrogen atom in the 6f state, what is the minimum angle between the orbital angular momentum vector and the z axis?
3. The red line of the Balmer series in hydrogen (A = 656.5 nm) is observed to split into three spectral lines with A = 0.040 nm between two adjacent lines when placed in a magnetic ?eld B. What is the value of B if A is due to the energy splitting between two adjacent m/ states?
Two point charges q units each placed 2 m apart exert a force the f 20 N on eaother. What will be the force between them if third charge -q units is placed at the mid point of the link be joining the two charges?
Physics - Speed and Direction, Driving along a crowded freeway, you notice that it takes a time t to go from one mile marker to the next.
What should the charge (sign and magnitude) of a particle of mass 1.44 be for it to remain stationary when placed in a downward-directed electric field of magnitude 630 ? Use 9.81 for the magnitude of the acceleration due to gravity.
