Im not sure what to do for this question...the "original position" is the top picture. The next question asks if the balls with double the mass were moved to the positions in the second picture if the force of attraction would increase or decrease by 8x or 16x.

Before move After move E Two balls with equal moss, M, are at rest on a horizontal table. The distance between their centers is r, and the force of attraction between them is F. The balls are then returned to their original positions and they are replaced with two new balls, each of which has double the mass. How will the force of attraction between the balls change? It will increase by a factor of 2 It will decrease by a factor of 2. It will increase by a factor of 4. It will decrease by a factor of 4
