Q. Find out the energy of an x ray produced when an electron moving at 3 Mm/s is suddenly brought to rest. Express your answer in J.

Q. Two small insulating spheres with radius 9×10-2 are separated by a large center-to-center distance of 0.52. One sphere is negatively charged, with net charge -2.4, and the other sphere is positively charged, with net charge 3.2. The charge is uniformly distributed within volume of each sphere.
