Question

4. Give two examples of charging an uncharged object by friction.
5. What is GLE? Draw a diagram of GLE and label its parts.
6. How can we determine the magnitude of charge on an object using an electroscope?​

Answer 1

Answer:

Ans - 1 Most objects are electrically neutral, which means that they have an equal number of positive and negative charges. In order to charge an object, one has to alter the charge balance of positive and negative charges. There are three ways to do it: friction, conduction and induction.

Ans -2 ?????

Ans - 3 Vigorously rub the uncharged glass rod with a paper towel to give it a positive charge. 4.) bring the positively charged rod close to the Electroscope. If the leaves are repulsed, then you know that the glass rod of unknown charge was/is of the same charge, and therefore is positively charged.
