A particle moves in a force field described by the Yukowa potential V (r) = −k/r exp(−r/a) where k and a are positive. Write the equations of motion and reduce them to the equivalent one-dimensional problem. Use the effective potential to discuss the qualitative nature of the orbits for different values of the energy and the angular momentum.

Question

A particle moves in a force field described by the Yukowa potential
V (r) = −k/r exp(−r/a)
where k and a are positive.

Write the equations of motion and reduce them to the equivalent
one-dimensional problem. Use the effective potential to discuss the qualitative nature of the orbits for different values of the energy and the angular momentum.
