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

proton (mass = 1.67x10-27kg) is confined in a one dimensional potential well of infinite height and width of 2.847 x10-14m. Calculate the kinetic energy of the proton in the state with quantum number 1 in MeV

2. Relevant equations

KE = ((h^2)*(n^2))/(8*m*L^2) = ans / 1.6E-13 = ans in Mev

3. The attempt at a solution

((6.6E-34^2)*(1^2))/(8*1.67x10-27*2.847 x10-14^2)=1.7368E-14/1.6E-13=.10855

this answer is wrong, im not sure why or what im doing wrong. please help
