Apoint charge of −3.50 µc is located in the center of a spherical cavity of radius 5.00 cm inside an insulating charged solid. the charge density in the solid is ρ = 7.35 × x10−4 c/m3 . calculate the electric field inside the solid at a distance of 10 cm from the center of the cavity.

Certain bacteria (such as aquaspirillum magnetotacticum) tend to swim toward the earth’s geographic north pole because they contain tiny particles, called magnetosomes, that are sensitive to a magnetic field. if a transmission line carrying 100 a is laid underwater, at what range of distances would the magnetic field from this line be great enough to interfere with the migration of these bacteria? (assume that a field less than 5% of the earth’s field would have little effect on the bacteria. take the earth’s field to be 5.0 * 10-5 t, and ignore the effects of the seawater.)
