Masses of 1kg each are placed 1m, 2m, 4m, 8m, ... from a point P. The gravitational field intensity at P due to these masses is
Infinite no.of bodies, each of mass 3kg are situated at distances 1m, 2m, 4m, 8m....... respectively on x-axis. The resultant intensity of gravitational field at the origin will be
Infinite number of bodies, each of mass 2kg are situated on X-axis at distance 1m, 2m, 4m, 8m and so on, respectively from the origin. The resulting gravitational potential due to this system at the origin will be:
