A spring is rigidly attached to a wall. At the end of the spring there is a charge + 20 μC. On a seperate wall there are three charges fixeda distance 0.8 m apart. All of the charges are equal in magnitude. The central negative charge is a distance 1.93 m from the final positionof the charge attached to the spring. You can ignore any effect due to mass.

Has the spring stretched or compressed from it's equilibrium length (the length it would have if there are no charges)? (a) stretched (b) compressed How much has the spring stretched/compressed from it's equilibrium position if the spring constant of the spring is 10 N/m
