Write down the time-independent schrödinger equation of a particle with mass m confined in a central potential -1/r. use spherical coordinates.

2. write down the time-independent schrödinger equation of two particles with masses m_1 and m_2 that are attracted to each other by potential -1/r_12 , where r_12 is the particle-particle distance, namely, r_12 = sqrt((x_1 - x_2)^2+(y_1 - y_2)^2+(z_1 - z_2)^2) , where particle 1’s coordinates are (x_1, y_1, z_1) and particle 2’s coordinates are (x_2, y_2, z_2).

neither accurate nor precise.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
