# Question

An electron and a proton each have a momentum of 3.28470 x 10-30 kg ∙ m/s ± 10-30 kg ∙ m/s.

(a) The minimum uncertainty in the position of the electron compared with that of the proton will be (1) larger, (2) the same, (3) smaller. Why?

(b) Calculate the minimum uncertainty in the position for each.

## Answer to relevant Questions

An electron and a proton are moving with the same speed. (a) Compared with the proton, will the electron have (1) a shorter, (2) an equal, or (3) a longer de Broglie wave-length? Why? (b) If the speed of the electron and ...The energy of a 2.00-keV electron is known to within ± 3.00%. How accurately can its position be measured? An electron traveling at 3.00 x 104 m/s is further accelerated by a potential difference so as to reduce its de Broglie wavelength to one-third of its original value. How much voltage is required to accomplish this? Electrons are accelerated from rest through an electric potential difference. (a) If this potential difference increases to four times the original value, the new de Broglie wavelength will be (1) four times, (2) twice, (3) ...Using the general guidelines for nuclear stability, explain why aluminum has only one stable isotope (27Al). In other words, why aren’t isotopes of aluminum, such as 28Al or 26Al, stable?Post your question
