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 stre...

Three charges are located at the corners of a rectangle as follows: Charge A: lower left corner, -3.0 μC Charge B: upper left corner, -6.1 μC Charge C: upper right corner, +2.7 μC The distance between A and B is 0.16 m and between B and C it is 0.25 m....

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. G...
