Edexcel unit 5 question

I've got a past paper of unknown year and I don't have mark scheme for it. Please can someone help me with this question

Add to the diagram below three equipotential surfaces which have equal changes of potential between them.

Does it mean I don't have to draw the concentric circles getting further apart?

The change in the gravitational potential energy of the satellite when it moves to a different orbit might be calculated using the expression ' weight of satellite X change in heighgt'.
What condition must apply for this to be valid? Explain your answer.

3 concentric circles with increasing seperation between them.

The g field must be uniform. For this to occur changes in height must be small.

Regards.

agreed

this is the jan 05 unit 5 paper if im not mistaken. u can download the markscheme off edexcel international webpage.
p.s make sure its edexcel international not the uk one
