According to the Heisenberg uncertainty principle, if the uncertainty in the speed of an electron is 3.5 x 10^{3} m/s, the uncertainty in its position (in m) is at least (mass electron = 9.11 x 10^{-31} kg) __.

A) 1.7 x 10^{-8} m

B) 6.6 x 10^{-8} m

C) 17 m

D) 66 m

E) None of these choices is correct
