The table below gives the masses of the Earth, the Moon, and the Sun. Name Mass (kg)
Earth 5.97Ɨ1024
Moon 7.35Ɨ1022
Sun 1.99Ɨ1030
G is the universal gravitational constant, whose numerical value (in SI units) is 6.67Ɨ10^(āˆ’11)Nā‹…m2kg2.
The average distance between the Earth and the Moon is 3.84Ɨ10^8m . The average distance between the Earth and the Sun is 1.50Ɨ10^11m . Use this information to answer the following questions.
1. Find the net gravitational force Fnet acting on the Earth in the Sun-Earth-Moon system during the new moon (when the moon is located directly between the Earth and the Sun).
Express your answer in newtons to three significant figures.
2.Find the net gravitational force Fnet acting on the Earth in the Sun-Earth-Moon system during the full moon (when the Earth is located directly between the moon and the sun).
Express your answer in newtons to three significant figures.

Three different objects, all with different masses, are initially at rest at the bottom of a set of steps. each step is of uniform height . the mass of each object is a multiple of the base mass : object 1 has mass 4..00m , object 2 has mass 1..96m , and object 3 has mass . when the objects are at the bottom of the steps, define the total gravitational potential energy of the three-object system to be zero. if the objects are then relocated as shown, what is the new total potential energy of the system? each answer requires the numerical coefficient to an algebraic expression. each algebraic expression is given using some combination of the variables , , and , where is the acceleration due to gravity. enter only the numerical coefficient. (example: if the answer is 1..23mgd , just enter 1.23)
