Question

Problem 3.20 Your answer is partially correct. Try again. A planet of mass 7 x 1024 kg is at location -9 x 1011, 2 x 1011, 0> m. A star of mass 6 x 1030 kg is at location <4 x 1011,-3 x 1011, 0> m. What is the force exerted on the planet by the star? (It will probably be helpful to draw a diagram, including the relevant vectors.) on planet 321230 1235500 > N(a) Calculate the magnitude of the gravitational force exerted by Venus on a 84 kg human standing on the surface of Venus. (The mass of Venus is 4.9 x 1024 kg and its radius is 6.1 106 m.) T738.25 (b) Calculate the magnitude of the gravitational force exerted by the human on Venus. 738.25 the tolerance is +/-590 (c) For comparison, calculate the approximate magnitude of the gravitational force of this human on a similar human who is standing 2.0 meters away. 1.0677e-7
