The resultant od the horizontal forces is the driving force from the engine (answer 4). Force C. is 30N, force D. is 20N, and therefore the horizontal resulting force is 30N - 20N = 10N. This is the force which makes the car driving forward, and therefore the driving force for the engine.
So the problem are asking to find the value of G base on the formula of the said equation of the magnitude of gravitational attraction on either body. Base on that, the possible answer or the derived formula of the said function is G = Fr^2/m1m2. I hope you are satisfied with my answer and feel free to ask for more
Answer:
weight is the mass of an object
it is depends on mass of the body.
