Calculate the uncertainty in the position (in A) of an electron moving at a speed of (6.5 +/- 0.1)* 10^5m/s. The mass of an electron is 9.109x10^-31 kg.

Thanks!

DxDp = h/4p

Where Dx is uncertainty of position, Dp is uncertainty in momentum, h is Planck's constant 5.26e-33 Joule seconds, and p is linear momentum, P = mv.
