A spherical cavity of radius \( 5.00 \mathrm{~cm} \) is at the center of a metal sphere of radius \( 170 \mathrm{~cm} \) A point charge \( 3.90 \mu \mathrm{C} \) rests at the very center of the cavity, whereas the metal conductor carries no net charge. Part A Determine the electric field at a point \( 3.00 \mathrm{~cm} \) from the center of the cavity. Part B Determine the electric field at a point \( 650 \mathrm{~cm} \) from the center of the cavity Part C Determine the electric field at a point \( 30 \mathrm{0} \mathrm{cm} \) from the center.
