what is Gravitational field at a distance r from the infinitely long rod with liner mass density d? Please drive it Ans) use Gauss'' law of electrostatics, but replace (1/4πε0)
Like the centre of mass, the moment of inertia is a function of a body that is concurrent to its mass distribution. Moment of inertia gives a measurement of the resistance of a bod
