Question

Imagine three electrically charged particles, all within five centimeters of each other. Assume that the space around the charged particles is a vacuum.

5) Which options below are true?

A) The strength of the total electric field extremely far away from the collection of particles is close to zero. B) Electric field vectors only exist in the space right next to the charged particles. C) The electric force on a negatively charged target particle a small distance away from the sources will point in the same direction as the electric field created by the sources at target location. D) The electric field at a target location in space only depends on the properties and positions of the source charges and the location of the target. E) None of the above

Consider a pair of charged particles, particles 1 and 2, separated by a distance r. Which options below are true? A) Particle 2's electric field does not contribute to the electric force on particle 1. B) Particle 1's electric field does not contribute to the electric force on particle 1. C) If particle 2 were removed, there would still be a non-zero electric field at its location. D) If particle 2's distance from particle 1 is tripled, particle 1's electric field at 2's new location is no different than before since the field does not depend on the the properties of particle 2. E) None of the above
