Anelectroscopeis an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The firstelectroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.
Uses of electroscope are-
1.Electroscopes detect electric charge by the motion of a test object due to theCoulomb electrostatic force.
2.it is used to find the nature of charge
