3·The distance between two plates of capacitor is 1cm and potential difference 1200V between them. If an electron of energy 2000 eV enters at right angle to the field of capacitor midway between the plates, what will be its deflection if the plates are 1.5cm long?
Find the distance between an electron and a proton if the electric force between them is 82.4 nN.
Calculate the distance between a proton and an electron where the electrostatic force between them is equal to the average weight of both particles. The following may be useful: mass of the proton = 1.7 x 10-27 kg, mass of the electron = 9.1 x 10-31 kg, and charge of the electron = charge of the proton = 1.6 × 10-19 C. m
6. Delocalization energy, DE, can be defined as the difference between the calculated value for the total pi-electron energy and "the sum of its parts". For example, DE for 1,3-butadiene Er(calculated) ET for two ethylenes; for benzene, its Er(calculated) - Er for three ethylenes, etc. (note that the total pi- energy for each ethylene is 2a + 2B) (a) Given that the eigenvalues for benzene are: a +2B and a B, calculate DE for benzene (b) One often reads that...
If the masses of two planets doubles and the distance between them reduces by half, the force between them would be
An electron-positron pair is produced by a 2.30 MeV photon. What is the kinetic energy of the positron if the kinetic energy of the electron is 0.958 MeV? Use the following Joules-to-electron-Volts conversion 1eV = 1.602 × 10-19 J. The rest mass of an electron is 9.11 × 10-31 kg
An electron with kinetic energy 228 eV is moving in a horizontal direction. The electron moves into a region where there is a uniform vertical electric field which has magnitude 3990 N/C. Find the smallest magnitude of a magnetic field that will cause the electron to continue to move horizontally. (1eV=1.6^10^(-19)J;mass of the electron=9.11*10^(-31)kg)
An electron-positron pair is produced by a 2.85 MeV photon. What is the kinetic energy of the positron if the kinetic energy of the electron is 1.219 MeV? Use the following Joules-to-electron-Volts conversion 1eV = 1.602 × 10-19 J. The rest mass of an electron is 9.11 × 10-31 kg Please answer in MeV
1) What is the electrostatic potential energy (in joules) between an electron and a proton that are separated by 56 pm? 2) What is the change in potential energy if the distance separating the electron and proton is increased to 1.0 nm?
The electric force between two charges quadruple if the distance between them halves (True,False)
