A negatively charged balloon is brought near a neutral conducting sphere as shown below. As it approaches, charge within the sphere will distribute itself in a very specific manner. Which one of the diagrams below properly depicts the distribution of charge in the sphere? Encircle the letter of the correct answer. b. d.arrow_forwardLearning Goal: To understand how to calculate forces between charged particles, particularly the dependence on the sign of the charges and the distance between them. Coulomb's law describes the force that two charged particles exert on each other (by Newton's third law, those two forces must be equal and opposite). The force F21 exerted by particle 2 (with charge q2) on particle 1 (with charge q₁) is proportional to the charge of each particle and inversely proportional to the square of the distance r between them: Figure F21 particle 0 = k 92 91 p2 1 where k = and 21 is the unit vector pointing 4περ from particle 2 to particle 1.

What about on either side of the parallel plates? Explain in terms of force. For this question, I assume the test charge is positive and that the force would point in the direction of the electric field (high to low toward the negatively charged plate). If placed outside of the positive plate, I assume the force would travel in the same direction as the E-Field (high to low). If on the other side of the negative plate, wouldn't the force travel opposite to the E-field lines?arrow_forward
