 Assume that you are supplied with a translational potentiometer sensor with the following properties;

* 100 V DC Power Supply,

* 1 resistive wire: 40 mm long with 1mm² cross-section area. ( resistivity=0,00025 Ohm m)

 It is also given to you that;

 -In the initial state (where no force is applied to the system) of the potentiometer, movable arm of the output voltage positioner covers 90% (length) of the resistive wire.

- When 10N of force is applied to the system you observe 6mm displacement (in (-) y direction) of the movable arm of the output voltage positioner

Calculate what is the output voltage change caused by the 10N of force?
