Physics (AS & A Level) · May / June 2023 · Paper 12 · Question 19

A child holds a thin metal wire that is attached to a kite. The graph shows how the extension of the wire varies with its tension. A gust of wind increases the tension from 100 N to 150 N. What is the change in the elastic potential energy of the wire caused by the gust of wind?
