Draw the pattern of the gravitational flux passing through a horizontal surface, a, of area 1 m2 close to the earth's surface. [3 marks] b. what is meant by the phrase "gravitational potential at a point in a gravitational field"? [2 marks] c. explain why the surface a is an equipotential surface. [2 marks] d. if a surface b, situated 2.00 m directly below a and parallel to a, is taken to be at zero gravitational potential, what is the potential of surface a? take the acceleration of free fall at the earth's surface to be 10.0 m s-2, [2 marks] e. if a body is allowed to fall from surface a to surface b along a smooth, curved path, what will be its velocity on reaching surface b?
