Part C The magnitude of the electric field 1 m away from the positive charge is the magnitude of the electric field 2 m away. • View Available Hint(s) two times four times equal to one-half one-quarter Submit Previous Answers Correct The magnitude of the field decreases more quickly than the inverse of the distance from the charge. The magnitude of the electric field is proportional to the inverse of the distance squared (E x 1/r2, where r is the distance from the charge). You should verify this by looking at the field strength 3 or 4 meters away. This is consistent with Coulomb's law, which states that the magnitude of the force between two charged particles is F = KQ1Q2/r² . Part D If the field strength is E = 9 V/m a distance of 1 m from the charge, what is the field strength E a distance of 3 m from the charge? • View Available Hint(s) E = .56 V/m Submit Previous Answers
