2 A simple electroscope​

Answer» <html><body><p>tion:The electroscope is an early scientific instrument used to detect the <a href="https://interviewquestions.tuteehub.com/tag/presence-25557" style="font-weight:bold;" target="_blank" title="Click to know more about PRESENCE">PRESENCE</a> of <a href="https://interviewquestions.tuteehub.com/tag/electric-967871" style="font-weight:bold;" target="_blank" title="Click to know more about ELECTRIC">ELECTRIC</a> charge on a body. It detects charge by the movement of a test object due to the Coulomb <a href="https://interviewquestions.tuteehub.com/tag/electrostatic-2069468" style="font-weight:bold;" target="_blank" title="Click to know more about ELECTROSTATIC">ELECTROSTATIC</a> 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 <a href="https://interviewquestions.tuteehub.com/tag/sources-1219409" style="font-weight:bold;" target="_blank" title="Click to know more about SOURCES">SOURCES</a> 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.</p></body></html>
