State similarity and difference between the electric field lines and the gravitational field lines around an isolated positively charged metal sphere.
The lines are radial and as distance increases from the sphere the further away the lines get from each other in both.
The differences are that gravitational lines are directed towards the sphere and electrical are directed away from the sphere
