1. Coulomb was able to measure the different electric forces between two charged spheres and how this varied with both the charge and the distance between the mm the spheres. a) What did he discover happened to the force when the charge on one sphere was halved? b) What did he discover happened to the force when the charge on both spheres was halved? c) What happened to the force when the distance between the spheres was halved? d) Write an equation that links the force, the charges and the distance between their W
