An electron is 0.5 Å away from a carbon nucleus which contains 6 protons. Find the mutual force of attraction between the nucleus and the electron. 1Å (Angstrom)= 10^-10m, e=1.6x10^-19C.

9:54 Sat 14 May 令7€ 1. History: Robert A. Millikan's oil drop experiment in the early 1900s is historically famous, because. a) it discovered the existence of electrons. it provided experimental evidence for the existence of an electron. it revealed that electrons are negatively charged. b) c) d) it estimated the value of the fundamental charge. field is

1. Consider a simple ionic drive. a) If the drive field is 10,00OV/m what is the force on the spacecraft from a singly ionized charge being accelerated. b) Assume the electrical length of the engine is 0.2m. Find the impulse from this charge if the charge is accelerated at a constant acceleration. (Mcharge = 2.2e-23kg) c) Find the force of one mole of nitrogen atoms through this engine. d) Find the impulse of one mole of nitrogen atoms through this engine. e) Find the electrical current and power needed to drive such a device.

Options:  a) Neither, both have the same final KE b) the proton The answer is (a) neither, but I am struggling to understand why. I included my work, so maybe you can help me understand where I am going wrong.  Things we know:  KE = 1/3 MV^2 Mass of electron : 9.1 x 10^-31 kg (smaller) Mass of proton: 1.67 x 10^-27 kg (larger) Force = same magnitude for both since they both have the same magnitude of charge in the same Efield F=ma

The electronic structure of atoms and molecules may be investigated using photoelectron spectroscopy. An electron in a photoelectron spectrometer is accelerated from rest by a uniform electric field to a speed of 420 km s−1 in 10 µs. Determine the kinetic energy of the electron?     a. 8.0 x 10-20 N.m       b.  1.6 x 10-25 N.m       c. 3.8 x 10-25 N.m       d. 4..0 x 10-2 N.m

36. * BIO Body cell X-ray a. A body cell of 1.0 × 10-5-m radius absorbs 4.2 × 10-14 J of X-ray radiation. If the energy needed to produce one positively charged ion is 100 eV, how many positive ions are produced in the cell? b. How many ions are formed in the 3.0 × 10-6-m-radius nucleus of that cell (the place where the genetic information is stored)? Indicate any assumptions that you made.

In the famous “oil drop experiment,” Robert Millikan exposed oil drops to X-rays to remove electrons from them and then suspended them in mid-air using an electric field. The experiment determined the “fundamental charge” of the electron. Answer the following questions about the experiment without copying things from the text or from the internet.In other words, demonstrate an understanding of the scientific principles behind the experiment: a. Why did an electric field make the oil drops float in mid-air? b. How did the strength of the electric field and the masses of the oil drops lead Millikan to the value of the “fundamental charge” of the electron?
