Mcq on centre of gravity
WebAnswer. Acceleration due to the earth's gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. As the distance from the centre decreases, the acceleration due to gravity also decreases. WebCONCEPT OF Center of Gravity & Center of Mass The center of gravity (G) is a point which locates the resultant weight of a system of particles or body. From the definition of a resultant force, the sum of moments due to individual particle weight about any point is the same as the moment due to the resultant weight located at G.
