(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Question 1) Calculate the de Broglie wavelength of a neutron (mn = 1.67493×10-27 kg) moving at one fiftieth of the speed of light (c/50).

Question 2) Calculate the velocity of an electron (me = 9.10939×10-31 kg) having a de Broglie wavelength of 225.7 pm.

2. Relevant equations

Wavelength of a particle = Plancks constant/(mass)(velocity)

Plancks constant= 6.626068 x 10^-34

I know this, and it should be plug and chug but my answer is always wrong...any help would be greatly appreciated!

3. The attempt at a solution
