A Uranium 235 atom has 92 protons in the nucleus and has a mass of 3.92 E-25 kg. A) How many Uranium atoms would you need to have 1.00 Coulombs of protons? B) What mass of Uranium would that be?

8) The nucleus of a silver atom has a charge +47 e and is fixed at the origin of a cartesian coordinate system. An alpha particle of mass 6.68 × 10^−27 kg and charge +4 e is fired along the x-axis from infinity with an initial kinetic energy of 7.00 × 10^−13 J. At what distance from the silver nucleus will the alpha particle come (momentarily) to rest?

1.A parallel plate capacitor has square plates of side 8 cm and separated by a distance of 2 mm. (a) Calculate the capacitance of this capacitor. (b) If a 13 V battery is connected to the capacitor, what is the charge stored in any one of the plates? (The value of ɛo = 8.85 x 10-12 Nm2 C-2) 2.A beam of protons moves in a circle of radius 0.25 m. The beam moves perpendicular to a 0.30 T Magnetic field. (a) What is the speed of each proton? (b) Determine the magnitude of the centripetal force on each proton. The mass of a proton is mP = 1.67 x 10 27 kg and it has a charge of +e where e = 1.609x 10 19 C.
