An electron starting from rest acquires 1.34 keV of kinetic energy in moving from point A to point B. 1) How much kinetic energy would a proton acquire, starting from rest at B and moving to point A? 2) Determine the ratio of their speeds at the end of their respective trajectories.
QUESTION 26 During a Compton interaction, a secondary electron with a binding energy of 1.7 keV is ejected from an atom with 4 keV of kinetic energy. If the scattered x-ray has an energy of 58 keV, what was the energy of the incident X- ray? Give your answer in keV, rounded to the nearest tenth. But do not include the unit - give only the number portion of your answer. 1 points Save Answer
An electron and a proton are a distance r = 2 × 10-9 m apart. How much energy is required to increase their separation by a factor of 9?
A photon having E = 37.7 keV energy scatters from a free electron inside a metal. What is the maximum energy the electron can gain from the photon? At which angle will the photon scatter with respect to its original direction? (The accepted unit abbreviations for angles are either 'deg' for degrees or 'rad' for radians.) At which angle will the electron scatter?
9. In a hydrogen atom a single electron orbits a proton at a radius of 0.05 nm. a. What’s the potential at this distance from the proton? b. How much electric energy is stored in the atom, in both eV and J?
An electron and a proton, each starting from rest, are acceae by the same uniform electric fleld of 235 N/C. Determine the distance d (in m) and time t (in s) for each particle to acquire a kinetic energy of 3.1 x 10 electron d proton d-
The electron and the proton in a hydrogen atom are about 10−10m from each other. Determine the magnitude of the electric force exerted on an electron.
Determine the magnitude of the force between an electric dipole with a dipole moment of 9 ✕ 10-29 C m and an electron. The electron is positioned r = 28 nm from the centre of the dipole, along the dipole axis. Hint: Assume that r >> d, with d the charge separation distance in the dipole.
A particular electric dipole consists of a proton of charge of 1.6x10-19 Coulomb and an electron of charge of -1.6x10-19 Coulomb, separated by 2x10-10[m] = 0.2[nm]. 1a. What’s the electrostatic force between the charges (magnitude and direction), and why? 1b. What’s the electric field magnitude and direction at a point halfway between the two charges, and why? 1c. How much energy (in electron Volts OR in Joules) is needed to separate these two charges? 1d. If these two charges “fell...
Suppose the magnitude of the proton charge differs from the magnitude of the electron charge by a mere 1 part in 10^9. A) What would be the force between two 1.1-mm-diameter copper spheres with 2.0 cm between their centers? Assume that each copper atom has an equal number of electrons and protons. Express your answer to two significant figures and include the appropriate units. B) Would this amount be detectable? C) What can you conclude from the fact that no...
