On October 17, 2006, the population of the United States reached 300. million. If all of those people jumped up in the air simultaneously, pushing Earth with
an average force of 800. N each for a time of 0.10 s, what would happen to the
5.98 10^24 kg Earth?

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
