Heisenberg Uncertainty principle is applicable to      

$\Delta V=\frac{h}{4\pi .m.\Delta x}=\frac{6.65\times {10}^{-34}}{4\times 3.14\times 9.1\times {10}^{-31}\times {10}^{-11}}$ $=5.79\times {10}^{6}m/s$

Heisenberg Uncertainty principle is applicable for microscopic particles not macroscopic particles.

Hence, the correct option is b.
