An alpha particle (mass 6.6 x 10^-24 grams) emitted by radium travels at 3.4 x 10^7 plus or minus 0.1 x 10^7 mi/h.

(a) What is its de Broglie wavelength (in meters)?

(b) Whats uncertainty in its position?

for part a I got -3.41 x 10^6 meters which said it was wrong and I don't know how to do part b.
