Question

2 charged objects p and q are brought close to electroscope one by one . whn p is brought close to electroscope it leads diverge and whn q is brought near it , it leaves collapse . Identify the charges p and q

Answer 1

An electroscope is a simple apparatus which is used to measure the static electricity or the electrical charges that are freely flowing in the atmosphere. So, if the electroscope is positively charged then it will repel the same charge and attract the opposite charge. Therefore, for a positively charged electroscope, charge $p$ is positively charge as it diverges away from the electroscope and charge $q$ is negatively charge as it get collapsed in it.
