What would the speed of a proton (mass = 1.67 x 10g) have to be in order to have the same wavelength as an electron (mass = 9.11 x 10-** g) travelling at a speed of 2.74 x 10 m/s? Ans. m/s
Calculate the de Broglie wavelength of an electron with a speed of 2.75 x 107 km/hr and a mass of 9.11 x 10–28 g.
Find the de Broglie wavelength λ for an electron moving at a speed of 1.00×106m/s. (Note that this speed is low enough that the classical momentum formula p=mv is still valid.) Recall that the mass of an electron is me=9.11×10−31kg, and Planck's constant is h=6.626×10−34J⋅s.
An electron of mass 9.11 10-31 kg has an initial speed of 2.85 105 m/s. It travels in a straight line, and its speed increases to 6.93 105 m/s in a distance of 5.50 cm. Assume its acceleration is constant. (a) Determine the force exerted on the electron. (b) Compare this force with the weight of the electron, which we neglected. F weight of the electron =
