A mountain 10.0 km from a person exerts a gravitational force on him equal to 2.00% of his weight.(Of course, there could be an unknown force acting, but scientists first need to be convinced that there is even an effect, much less that an unknown force causes it.) How does the force of Jupiter on the baby compare to the force of the father on the baby? Other objects in the room and the hospital building also exert similar gravitational forces. (b) Calculate the force on the baby due to Jupiter if it is at its closest distance to Earth, some 6.29 x 10 11 m away. (a) Calculate the gravitational force exerted on a 4.20-kg baby by a 100-kg father 0.200 m away at birth (he is assisting, so he is close to the child). The only known force a planet exerts on Earth is gravitational. Astrology makes much of the position of the planets at the moment of one’s birth.Estimate the gravitational force between two sumo wrestlers, with masses 220 kg and 240 kg, when they are embraced and their centers are 1.2 m apart.Evaluate the magnitude of gravitational force between two 5-kg spherical steel balls separated by a center-to-center distance of 15 cm.What does this say about space as you approach the black hole?ġ3.1 Newton's Law of Universal Gravitation (The person falling into the black hole sees their own processes unaffected.) But the speed of light is the same everywhere for all observers. As a person approaches the Schwarzschild radius of a black hole, outside observers see all the processes of that person (their clocks, their heart rate, etc.) slowing down, and coming to a halt as they reach the Schwarzschild radius. ![]() (View this from a nonaccelerating frame outside the lab.) Relative to the height of the laser, where will the laser beam hit the far wall? What does this say about the effect of a gravitational field on light? Does the fact that light has no mass make any difference to the argument? For the latter case, consider what happens to a laser beam at some height shot perfectly horizontally to the floor, across the accelerating lab. The principle of equivalence states that all experiments done in a lab in a uniform gravitational field cannot be distinguished from those done in a lab that is not in a gravitational field but is uniformly accelerating.
