Question

explain why the graph given in downward quadrant is most correct....

Answer 1

hola dear as u can see that the graph on Y axis gives a perfect idea for the direction of gravitational field from point O to point B and then to infinity i..e point C........so the graph in upper quadrant is also correct but it doesn't give any idea for the direction of gravitational field as the downward graph gives......

so the graph in the lower quadrant is most perfect
