WebScience Physics Two point charges of mass m each are suspended in the gravitational field of the Earth by two non-conducting massless strings, each of length 1, attached to the same fixed point. The spheres are given equal charges Q of the same sign. As a result each string makes angle a to the vertical (see figure below). Calculate m, if 1 = 78.3 cm, Q = 4 …
WebApr 7, 2024 · The regions of intense gravity may have excited ... does not occur in a Minkowski background in a vacuum since the scalar field only enters the source term in the gravitational wave equation and ... Newton's description of gravity is sufficiently accurate for many practical purposes and is therefore widely used. Deviations from it are small when the dimensionless quantities and are both much less than one, where is the gravitational potential, is the velocity of the objects being studied, and is the speed of light in vacuum. For example, Newtonian gravity provides an accurate description of the Earth/Sun system, since
WebApr 1, 2011 · You are using the wrong gravitational constant. While it's true that at the surface of the Earth, the acceleration due to gravity is 9.8 m/s^2, this is NOT what should be used in the gravitational equation. You need to use the Gravitational Constant, G, which is true for all massive objects, not just the Earth. • P.M. Whelan, M.J. Hodgeson (1978). Essential Principles of Physics (2nd ed.). John Murray.
