OSCILLATORY MOTION
9. In Example 2 of Chapter 7 we found that the gravitational force on a mass m
inside a spherical earth of uniform density p is F = kr, directed toward the cen-
ter, with k = TGpm.
(a) For a mass dropped from the surface of the earth down a tunnel straight through
the center of the earth, find the time T, to pass entirely through the earth and
back again.
(b) Compute the speed of the mass m as it passes through the center of the earth.
(c) Compare your result for T, with the time 72 required to complete a circular orbit
around the globe just above the earth's surface.
In this problem, you are going to explore three different ways to determine the gravitational constant G.
a) By observing that the centripetal acceleration of the Moon around the Earth is ac = 2.66 × 10-3 m/s2, what is the gravitatonal constant G, in cubic meters per kilogram per square second? Assume the Earth has a mass of ME = 5.96 × 1024 kg, and the mean distance between the centers of the Earth and Moon is rm = 3.81 × 108 m.
b) Measuring the centripetal acceleration of an orbiting object is rather difficult, so an alternative approach is to use the period of the orbiting object. Find an expression for the gravitational constant in terms of the distance between the gravitating objects rm, the mass of the larger body (the earth) ME, and the period of the orbiting body T.
c) The gravitational constant may also be calculated by analyzing the motion of an object, launched from the surface of the earth at an initial velocity of vi. Find an expression of the gravitational constant…

He published this theory—known as the general theory of relativity—in 1915. Einstein based the theory entirely on mathematics. He suggested a way of putting it to the test. He knew that the sun has a strong gravitational field. Its mass (about 1.99 × 10 30 kilograms) should not only affect the orbits of its planets but anything nearby. According to relativity, the sun’s gravitational field should bend light traveling to Earth from distant stars. Explain this in simpler terms.arrow_forward
