Analysis Model Tutorial A particle having charge q = +2.10 MC and mass m = 0.0100 kg is connected to a string that is L = 1.90 m long and tied to the pivot point P in the figure below. The particle, string, and pivot point all lie on a frictionless, horizontal table. The particle is released from rest when the string makes an angle 9 = 60.0 with a uniform electric eld of magnitude E = 290 V/m. Determine the speed of the particle when the string is parallel to the electric field. Part 5 of 5 - Analyze: (cont.)

Analysis Model Tutorial In 1911, Ernest Rutherford and his assistants Geiger and Marsden conducted an experiment in which they scattered alpha particles (nuclei of helium atoms) from thin sheets of gold. An alpha particle, having charge +26 and mass 6.64 x 10'27 kg, is a product of certain radioactive decays. The results of the experiment led Rutherford to the idea that most of an atom's mass is in a very small nucleus, with electrons in orbit around it. Assume an alpha particle, initially very far from a stationary gold nucleus, is fired with a velocity of 2.71 x 107 m/s directly toward the nucleus (charge +79e). What is the smallest distance between the alpha particle and the nucleus before the alpha particle reverses direction? Assume the gold nucleus remains stationary. Part 5 of 5 - Analyze: (cont.) (4) Based on the correct choice in question (3), substitute numerical values to find the distance of closest approach of the alpha particle to the gold nucleus. 316ke2 d = m v2 316(8.988 x 109 N . m2/C2) (1.60 x 10-19 C) 2 x 10-27 kg x 10-14 m x 107 m/S =Chase and Kadri consider the following values, which are part of a set of experimental data for a Millikan oil-droplet experiment. b = 1.48 x 1010 kg/s d = 0.016 m p0\" pair = 0.882 g/cm3 r= 3.0x 107 m V: 5000v What is the terminal speed for a droplet of charge 5e? :l m To what value should the voltage be adjusted so that the droplet is suspended between the two plates? :v
