Question

in the nucleus of helium if F1 is the net force b/w 2 protons,F2 is the net force b/w 2 neutrons and F3 is the net force b/w a proton and a neutron. then
1)F1=F2=F3
2)F1 greater than F2 greater than F3
3)F2 greater than F3 greater than F1
4)F2=F3 greater than F1

Answer 1

THE ANSWER TO THIS IS D

NET FORCE BETWEEN TWO NEUTRONS AND THE FORCE BETWEEN PROTON AND AN ELECTRON ARE EQUAL (AS IN AN ATOM PROTONS AND NEUTRONS ARE BOUND TOGETHER AS ONE UNIT) >F1 (AS YOU KNOW THAT ELECTRON REVOLVES AROUND THE NUCLEUS IT WOULDN'T HAVE BEEN POSSIBLE IF THE FORCE BETWEEN ELECTRON WERE GREATER THAN PROTONS AND ELECTRON S)

I HOPE THIS HELPS
