JEE Advanced 2020 Concept Recapitulation Test 4 Paper 2

A circular wire, 10cm in diameter, with a slider wire on it, is in a horizontal plane. A liquid film is formed, bounded by the wires, on the left side of the slider, as shown. The surface tension of the liquid is 0.1N∕m. An applied force 16mN, perpendicular to the slider, maintains the film in equilibrium. Ignore the sag in the film. What can be the distance between point F and slider?
