- Consider two imaginary spherical surfaces surrounding a point charge +Q. One is a sphere of radius 10 cm and the other is a sphere of radius 20 cm. Which statement about the net flux through these surfaces is correct? correct? The net flux through the larger sphere is the same as the net flux through the smaller sphere. The net flux through the larger sphere is half the net flux through the smaller sphere. The net flux through the larger sphere is four times the net flux through the smaller sphere. The net flux through the larger sphere is one fourth the net flux through the smaller sphere. The net flux through the larger sphere is twice the net flux through the smaller sphere.arrow_forwardA uniform charge of 16.0 mC is on a thin circular ring lying in an xy plane and centered on the origin.The ring’s radius is 3.00 cm.

- Early in the 20th century, a leading model of the structure of the atom was that of English physicist J. J. Thomson (the discoverer of the electron). In Thomson’s model, an atom consisted of a sphere of positively charged material in which were embedded negatively charged electrons, like chocolate chips in a ball of cookie dough. Consider such an atom consisting of one electron with mass m and charge -e, which may be regarded as a point charge, and a uniformly charged sphere of charge +e and radius R. By that time time, it was known that excited atoms emit light waves of only certain frequencies. In his model, the frequency of emitted light is the same as the oscillation frequency of the electron (s) problems in the atom. What radius (in millimeter) would a Thomson-model atom need for it to produce red light of frequency 4.57 x 1014 Hz?
