A body of mass mass 2500kg starts moving from rest and at certain point of time , it comes to a constant speed of 150000000m/s.Suppose, as soon as it comes to this speed,a stationary observer instantaneously calculates the gravitational force between the body and a nearby rock of mass 1200 kg, which is at a distance of 0.00005 m from the rock.If the person calculates the quantity correctly, what will be the sum of the non-zero digits of the answer ? For calculation take G= 7 * 10^-11(Nm^2)/kg^2
