a. Draw the electric field lines around a system that consists of two equal negative charges. b. Calculate the electric force that exists between two objects that are 7.3 × 10 –2 m apart and carry charges of 4.5 × 10 –6 C and –7.2 × 10 –6 C. Is this force attractive or repulsive? c. Write two or three sentences to explain the effect on the electric force between two charged objects if the amount of charge on one of the objects is doubled at the same time as the distance between the objects is doubled.
