A thin metallic spherical shell of radius 37.1 37.1 cm has a total charge of 6.75 μ C 6.75 μC uniformly distributed on it. At the center of the shell is placed a point charge of 2.63 μ C 2.63 μC . What is the magnitude of the electric field at a distance of 23.9 cm 23.9 cm from the center of the spherical shell?

Galileo was the first to notice that the moon has craters, valleys, and mountains. how might this have changed people's perception of the moon at the time?

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
