Question

2. Force on the Moon due to Sun and the Earth: Gravitational forces obey superposition, i.e. the net force on a mass is the vector sum of all the forces on the mass. The mass of the Sun is 2.0 × 103? kg. Suppose that the phase of the Moon is either in the first or third quarter, that is, the Moon makes a right angle with a line drawn from the Earth to the Moon. a. What is the magnitude of the gravitational force on the Moon due to the Sun? The distance from the Moon to the sun is much larger than the distance from the Moon to the earth. Therefore the distance from the sun to the Moon is almost the same as the distance from the sun to the Earth. b. What is the magnitude of the gravitational force on the Moon due to Earth? c. Draw a free body diagram showing the forces acting on the Moon. Represent the larger forces with a longer vector. d. What is magnitude of the net gravitational force on the Moon? e. What is the direction of the net gravitational force on the Moon? Give angle relative to the direction from the Moon to the Sun.
