Planet z-34 has a mass equal to 1/3 that of earth, a radius equal to 1/3 that of earth, and an axial spin rate 1/2 that of earth. with representing, as usual, the acceleration due to gravity on the surface of earth, the acceleration due to gravity on the surface of z-34 is g/9. 9g. g/3. 3g. 6g.

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
