Answer #1

AND NutEvS yis the variable dis tan ce element 8 oton penetrates nue ausơWhen the proton is accerarated it got its velocity , and initialy this velocity must must be increasing in nature but as the proton is reaching towards element B its velocity is decreasing dur repulsive force of nuceus of element B .

  • When the proton penetrates to the nucleus its final velocity comes to zero. On the hand potential energy of proton increases as it approaches towards nuleaus of Element B.

But energy of proton before and final will be same
