2019-05-10 Selkin TPHYS 121 122-03-01-b A positively-charged ring surrounds a negatively charged disc (both objects are insulators). The ring has a total charge of +5.0 nC; the disc has a total charge of-5.0 nC. The ring-disc assemblage has a radius of 0.2m, and the ring's thickness is negligible compared to the radius. Find the electric field 3 mm from the center of the assemblage. +5.0 nC pist 5.0 nC 3.0 mm z 10)

A uniformly charged ring and a uniformly charged disc each have a charge of +25 μC and a radius of 3.0 cm. For each of these charged objects, determine the electric field at a point along the axis 4.0 cm from the center of the object.
A Blu-ray disc has a mass of 20.0 g and a diameter of 120. mm. It takes 2.22 seconds for the Blu-ray player to get the disk up to speed from rest. Assume the operating speed of the Blu-ray disc is 10000 rpm (rotations per minute). Provide a diagram of the situation with coordinates. Calculate: a) Final angular momentum b) Work done to get disc up to speed
