Solution: According to the Heisenberg uncertainity principle , if the uncertainity in the speed of an electron is 3.5 x 103 m/s, the uncertainity in its position (in m) is at least:
A) 66 m
B) 1.7 x 10-8 m
C) 17 m
D) 2.1 x 10-10 m
E) 6.6 x 10-8 m

According to the Heisenberg uncertainity principle , if the uncertainity in the speed of an electron is 3.5 x 10^{3} m/s, the uncertainity in its position (in m) is at least:

A) 66 m

B) 1.7 x 10^{-8} m

C) 17 m

D) 2.1 x 10^{-10} m

E) 6.6 x 10^{-8} m
