જ્યારે  $\Delta x p$ માટે સરખું છે. ત્યાં $ \Delta p$  માટે 

$\frac{{\Delta {x_e} \times \Delta {p_e}\, \geqslant \,\frac{h}{{4\pi }}}}{{\Delta {x_{(He)}} \times \Delta {P_{He}}\, \geqslant \,\frac{h}{{4\pi }}}}\,\, = \,\,\frac{{\Delta Pe}}{{\Delta {P_{He}}}} = 1$

$\therefore \,\,\Delta {P_e}\,\, = \,\,\Delta {P_{He}}\,\,\, \Rightarrow \,\,\,32 \times {10^5}\,\, = \,\,32 \times {10^5}\,\,\,\, \Rightarrow \,\,\,\,\Delta {P_{He}}\, = \,\,32 \times {10^5}$
