A proton is accelerated to one-tenth the velocity of light, and this velocity can be measured with a precision of 1%. What is the uncertainty in the position of this proton?(speed of light = 2.998x10^8m/s;mass of proton = 1.673x10^-27kg;Planck's constant = 6.626x10^-34Js)
I only know that E = hf = hc/? = mc^2
h = mc?
6.626 x 10^-34 = (1.673 x 10^-27) x (2.998 x 10^8) ?
Is ? ((wavelength) means the position of proton? How to find uncertainty?Thank you
