1also in a multi-electron system . different attaract electron nucleus towards themselves thus there no net force on a nucleus.
according to bohr n others an e doesnt fall into nucleus as inward coulombic force is balanced by outward centrifugal force.Still a huge amount of attractive do exist between the nucleus and electron....the e is saved from falling into nucleus due to centrifugal force but what is it which saves the nucleus from accelerating towards the electron????

19its the centrifugal reaction force.....an example : when you whirl a stone by your fingers...the fingers experience the c.f. reaction force !!!!

49but my question was in an one e system like hydrogen why does the nucleus not accelerate towards the e.....
1Instead of considering it as Centrf.f=centrp.f,you can consider it like this that the amt. of centripetal force produced by the nucleus is just sufficient to rotate the e in a circular bohr orbit.The rest of the answer is like:" why an apple falls on the earth and the earth doesn't fall towards the apple?"
1i do not agree with this explanation......the apple is connected to the earth by the tree and lies within very short range of this massive earth.........nw consider this case......you and i are floating somewhere in empty universal space.......connected to each other by a string and both holding a space craft.......nw we keep on pulling each other through the string......after sometime i leave the space craft an so i am accelerated towards u as we r still pulling each other even if u stop pulling me and just hold the string n i try to pull u i m da one who will move as u r fixed........if i were fixed and u free whoever was pulling, it would be u who would accelerate irrespective of our masses because we dont have the hindering force called weight. so mass plays no function in such a case........................................... nw compare cases.........the electron pulls the proton towards itself.........the proton also attracts the electron equally strongly...........nw both dont accelerate towards the other. so we may conclude that as we were fixed to something which exerted a force to nullify our pulling effect so that we didnot fall into each other,,,,,,the electron and proton must also be have a backward force acting which hinders them from falling from each other........for the electron we may conclude that that the tangential tendency of e- to move away frm the nucleus due to circular motion saves it from falling into the nucleus, what is 'IT' that saves the nucleus from accelerating????????
same logic and question applies for the solar system..............
I am thinking on it since last 3 months or more but without much result.......how do u explain dis......
1i got it.......i got it......the electron never revolves round the nucleus.....but both the nucleus and the electron revolve around the centre of mass of the 2 particle system which lies motre towards the nucleus.....it being more heavy.....so the colombc attraction in e-is nullified by its perpendicular tendency to go away....n dat of the nucleus by its perpendicular tendency to move out........so both is kept intact in position....
am i correct.....if yes then reply........if no where was i wrong???????????
