    Q:

    		 A positive (q0) and a negative charge (q1) are placed in an electric field at a distance r from each other. A scientist measures the attractive force between the two and determines it to be F0. What changes to the system can be made in order to double the original force between the two charges?
    		 

    A

    		 Decrease q0 by half, and halve the original distance between the molecules

    B

    		 Double the original distance, and double both of the original charges

    C

    		 Halve the original forces, and decrease the distance by a factor of 4

    D

    		 Change q1 to a positive charge
