- 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? (You may wish to consider simple examples in which any other form would lead to contradictory results.)arrow_forwardIn this problem we are going to compare the strength of the gravitational interaction between the Moon and the Earth and the Sun and the Earth. We will do this by finding the gravitational field g due to the Moon or the Sun, which is the acceleration that the Earth would have if it were interacting with each of them. a) Calculate the magnitude of the gravitational field of the moon at the location of Earth, in meters per square second. b)Calculate the magnitude of the gravitational field of the Sun at the location of Earth, in meters per square second. c)Calculate the ratio of the gravitational field of the Sun to the gravitational field of the Moon, at the location of Earth.arrow_forwardA planet with mass of 7.50 x 1024) and Jupiter (m = 1.901 x 1027) are attracted to each other. However, they are in a long-distance relationship, being separated by a distance of 4.09 x 1014 meters. Calculate the force of attraction between these two planets.

- Newton’s universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. a) True b) Falsearrow_forwardA neutron star is a cold, collapsed star with nuclear density. A particular neutron star has a mass twice that of our Sun with a radius of 12.0 km. (a) What would be the weight of a 100-kg astronaut on standing on its surface? (b) What does this tell us about landing on a neutron star?arrow_forwardNewton's universal law of gravitation states that every particle in the universe attracts every other particle with a force along a line joining them. The force is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. Mathematically, it can be written as GMm F According to this law, when mass of both objects is doubled, the force r m becomes two times larger compared to original O becomes four times larger compared to original becomes quarter of the original O becomes half compared to originalarrow_forward
- What is the gravitational force exerted on a 50 kg by a 60 kg person standing two meters? What is the magnitude of the force exerted on the 60 kg person?arrow_forwarda) Calculate the magnitude of the gravitational force exerted by the Moon on a 65 kg human standing on the surface of the Moon. (The mass of the Moon is 7.4x1022 kg and its radius is 1.7x106 m.) b) Calculate the magnitude of the gravitational force exerted by the human on the Moon. c) For comparison, calculate the approximate magnitude of the gravitational force of this human on a similar human who is standing 4.5 meters away.arrow_forwardA recently discovered planet has a mass twice as great as Earth's and a radius twice as large as Earth's. What will be the approximate size of its gravitational field?arrow_forward
- The tallest spot on Earth is Mt. Everest, which is 8850 m above sea level. If the radius of Earth to sea level is 6369 km, how much does the gravitational field strength change between the sea level value at that location (9.826 N/kg) and the top of Mt. Everest? 9.798 O N/kgarrow_forwardNewton's Law of Gravitation says that the magnitude F of the force exerted by a body of mass m on a body of mass M is GmM F = where G is the gravitational constant and r is the distance between the bodies. (a) Find dF/dr. dF dr What is the meaning of dF/dr? dF/dr represents the rate of change of the distance between the bodies with respect to the force. dF/dr represents the rate of change of the force with respect to the distance between the bodies. dF/dr represents the rate of change of the mass with respect to the distance between the bodies. dF/dr represents the amount of force per distance. dF/dr represents the rate of change of the mass with respect to the force. What does the minus sign indicate? The minus sign indicates that the force between the bodies is decreasing. The minus sign indicates that as the distance between the bodies increases, the magnitude of the force increases. The minus sign indicates that as the distance between the bodies decreases, the magnitude of the…arrow_forwardThe gravitational force between two people is found to be 5.9 x 10-11 N. What would the gravitational force be between the two people if person A's mass is decreased to 1/3 the original value, person B's mass is increased to 3/2 of the original mass, and the separation distance between them is increased by a factor of 2?
