Rutherford, Geiger, and Marsden (his students) fired a beam of alpha particles at a gold foil. The alpha particles had an energy of about 3.6 million electron volts, a charge of +2e, and a mass of about four AMU (one Atomic Mass Unit is 1.66 x 10-27 kg. Gold has atomic number ...
Three charges are located at the corners of a rectangle as follows: Charge A: lower left corner, -3.0 Î¼C Charge B: upper left corner, -6.1 Î¼C Charge C: upper right corner, +2.7 Î¼C The distance between A and B is 0.16 m and between B an...
As a crude model for lightning, consider the ground to be one plate of a parallel-plate capacitor and the cloud to be the other plate. The altitude of the cloud is 600m and its area is 6.5 km2. How much charge can the cloud hold before the dielectric strength of air is exceede...
