Isaac physics D7.5 Physics Quantum kinetic energy
In the question Im given the wavelength in nm (3.0), the particle is a neutron, the momentum from the previous question is 2.2e-25. Using this I need to find the kinetic energy in eV.
I used the equation Ek= 1/2xMxV^2 and the mass a neutron aswell but I keep getting it wrong, even though this worked on the previous question.
Can anyone please help?
I used the equation Ek= 1/2xMxV^2 and the mass a neutron aswell but I keep getting it wrong, even though this worked on the previous question.

I got 9.06x10^-4 ev

I got 9.06x10^-4 ev
E = p^2 /2m where E is kinetic energy p is momentum and m is mass
E = (2.2x10^-25)^2 / 2 x 1.675x10^-27
E = 1.45x10^-23 J
then times by 1.6x10^-19 to convert to ev
E = 9.06x10^-4 ev
