In this problem we are going to compare the strength of the gravitational interaction between the Moon and the Earth and the Sun and the EarthWe will do this by finding the gravitational field due to the Moon or the Sunwhich is the acceleration that the Earth would have if it were interacting with each of themFor reference, the Moon has a mass of 7.34 * 10 ^ 22 kilograms and is located 3.84 * 10 ^ 5 kilometers away from the EarthThe Sunmeanwhile has a mass of 1.99 * 10 ^ 30 kilograms and is located 1.49 * 10 ^ 8 kilometers away from the Earth
Part a : calculate the magnitude of the gravitational field of the mood at the location earth in meters per square second
Part b: calculate the magnitude of the gravitational field of the sun at the location of earth, in meters per square second
Part c calculate the ratio of the gravitational field of the sun to the gravitational field of the moon , at the location of earth
Two books are on a shelf 1.3 m from one another. Book A has a mass of 2.2 kg. Book B hasa mass of 1.7 kg. A very naughty student sees the books while walking by. She tears somepages out of book A so that its new mass is 2.0 kg and sets it back on the same spot on theshelf.What effect does this have on the gravitational force between the books.AThe gravitational force increases because the mass of one book decreases.BThe gravitational force remains constant because the books remain in the same place.CThe gravitational force on book B decreases because the mass of book A decreases.DThe gravitational force on both books decreases because the mass of book A decreases.

- In the law of universal gravitation, Newton assumed that the force was proportional to the product of the two masses (m1m2) . While all scientific conjectures must be experimentally verified, can you provided arguments as to why this must be?

- Check Your Understanding Earth exerts a tidal force on the Moon. Is it greater than, the same as, or less than that of the Moon on Earth? Be careful in your response, as tidal forces arise from the difference in gravitational forces between one side and the other. Look at the calculations we performed for the tidal force on Earth and consider the values that would change significantly for the Moon. The diameter of the Moon is one-fourth that of Earth. Tidal forces on the Moon are not easy to detect, since there is no liquid on the surface.arrow_forwardIn a particle accelerator, a proton has mass 1.6710-27kg and an initial speed of 2.00105m/s .

Find the magnitude of the force exerted on the proton.arrow_forwardLet gM represent the difference in the gravitational fields produced by the Moon at the points on the Earths surface nearest to and farthest from the Moon.
