Example the ground state energy of 5 identical spin !!!! particles which are subjected to a 1d samplehamonic oscillator potential of frequency is (jest-2012) so

In question they only said to find the ground state energy only...but in example we find all the energy??? I didn't understand this thing

    usually in ques ,they give u electrons or sometimes ferminos.. I solved both cases.. there is a little difference in both cases.. in case of electron each state split into two as electrons has spin 1/2 so degeneracy of each state is 2. while in case of ferminos( u don't know which particular fermino they are taking about) so don't take spin and do ques normally without calculating degeneracy.. hope u will get me... best regards

    if they asked about the first state energy then how we will calculate..can you plz explain

    dear it contains these type of questions....from quantum mechanics they ask these type of intelligent type of questions. practice more n more.

    they asked difficult question or easy

    dear they asks both type of questions. and for a good rank we have to do both easy and hard. actually problem will not be hard when you practice them.

    we have to find all the particle energy according to their position

    did you get it?

    becoz dear we have 5 particles in ground state there can be only 2. remaining 3 will go to upper state. we are calculating ground state of 5 particle system. hope u get it .

    sorry i didn't get it

    eduncle-logo-app

    ok lemme explain

    eduncle-logo-app

    yes please explain me

    they said only ground state...so spin is 1/2 so in ground state their only 2 particle in ground state...but why we are calculating the energy of the above state
