which property is used ti identify the electric charge on the object?
coulomb electrostatic force
an electroscope is an early scientific instrument used to detect the presence of electric charge on a body. it detects charge by the movement of a test object due to the coulomb electrostatic force on it. the amount of charge on an object is proportional to its voltage. the accumulation of enough charge to detect with an electroscope requires hundreds or thousands of volts, so electroscopes are used with high voltage sources such as static electricity and electrostatic machines. an electroscope can only give a rough indication of the quantity of charge; an instrument that measures electric charge quantitatively is called an electrometer.

electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. there are two-types of electric charge: "positive" and "negative" (commonly carried by protons and electrons respectively). like charges repel and unlike attract. an object with an absence of net charge is referred to as "". early knowledge of how charged substances interact is now called classical electrodynamics, and is still accurate for problems that do not require consideration of quantum effects.
