Statement I ; Heisenberg's principle supports Bohr's theoryStatement II ; Heisenberg's principle is applicable to macro particles only

(I)According to Bohr's theory position and velocity of electron can be known simultaneously;According to Heisenberg, it is impossible to locate the exact position of electron and to know its exact velocity simultaneously;According to Heisenberg's principle it is only possible to know probable position and velocity of electron simultaneously;(II) Heisenberg principle is applicable to micro particles only;
