Answer» Centre of the gravity CJ of a body is the point about with the algebraic sum of the moments of weights of all the particles constituting the body is zero the entire weight of the body can be considered to act at this point how some howsoever the body is placed for EXAMPLE the position of a centre of a gravity of a body of a given mass DEPENDS on its shape for example on the distribution of a mass of a particles in it changes if the body is deformed for example the centre of gravity of a uniform WIRE is the time at the middle of the length but if the same wire is bent into the form of a Centre circle is centre of gravity will then be at the centre of the circle ...... !!!!!!!!!!!!!!!!!!!!!!!!!!! |
