7 A proton has kinetic energy 8.00 x 10-17 J. Which is the correct expression for the de Broglie wavelength 1 of the proton? 6.63 x 10-34 A /= 2 x 1.67 x 10-27 x 8.00 x 10-17 6.63 x 10-34 B /= 2 x 9. 11 x 10-31 x 8.00 x 10-17 6.63 x 10-34 C A= V2 x 1.67 x 10-27 x 8.00 x 10-17 6.63 x 10-34 D A= V2 x 9.11 x 10-31 x 8.00 x 10-17 Your
