One ring of radius R and mass m and one solid sphere of same mass m and same radius R are placed with their centres on positive x-axis. We are moving from some finite distance on negative x-axis towards positive x-axis plane of the ring is perpendicular to x-axis. How will the net gravitational field vary with distance moved on x-axis We move only up to surface of solid sphere. O is the origin.
