Sherlin wanted to study the dependence of the gravitational force of attraction between two bodies on the distance of separation. Therefore, she did the required calculations by keeping the masses of the two bodies constant and simply varying their distance of separation. She calculated the value of the gravitational force between those two bodies 10 times at different distances of separation. She then plotted a graph of the calculated data taking the force along the y-axis and the distance of separation along the x-axis. How would the graph look like?
