1. The following charges exist (given coordinates are (x, y) coordinates in the plane of the page): O a-3.0 C point charge located at (0, 0) a -2.0 C uniform spherical shell of charge of radius3.0 cm centered at (+4.0 cm, 0) a +2.0 C uniform spherical shell of charge of radius 2.0 cm centered at (0, -4.0 cm) a +4.0 uniform spherical shell of charge of radius 4.0 cm centered at (-1.0 cm, +1.0 cm) a. Calculate the net electric force (magnitude and direction) acting on the -3.0 C point charge. b. Suppose you were given a +1.0 C charge to add to the arrangement of charges above. Your goal is to place the charge so that the net force on the -3.0 C charge is zero. Where would you put the +1.0 C charge? Be specific. c. The -3.0 C point charge was created by either adding or removing electrons from a neutral object. Were electrons added or removed? How many electrons were added or removed? 1.

Answer rating: 100% (QA)

Given the complex arrangement of charges we can find the net electric force acting on the 30 C point charge using the principle of superposition which ... View the full answer
