ABSTRACT
Matters contain two types of charges such as positive and negative charges. Like matter, charges cannot also be created or destroyed, but rather transferred from one object to another. Rubbing materials together is the easiest way in order to charge them wherein one object will become negatively charged and the other one will become positively charged. Electric charges can be characterized by repulsion between two positive charges or two negative charges, and can also be attraction between a positive charge and a negative charge. In this experiment, we were able to determine the presence of electrostatic charges with the use of an electroscope. It is performed by using three different kinds of rod (plastic, glass, and PVC), each rubbed with silk cloth, flannel cloth, and fur cloth. The observations we have done brought about the idea that the rods and cloths that attracted confirmed the presence of opposite charges in them while the rods and cloths that repelled confirmed the presence of similar charges in them.
INTRODUCTION All matter contains positive and negative charges. Under normal circumstances, an object is “electrically neutral” which means that the number of positive charges that the object has is equal to the number of negative charges it has. An important principle to understand is that charge is conserved, meaning that charge is not created or destroyed, but rather transferred from one object to another. Rubbing materials together is the easiest way in order to charge them wherein one object will end up gaining electrons or will become negatively charged and the other one, since it loses electrons, will become positively charged. Electric charges are characterized by repulsion between like charges and attraction between opposite charges, which in particular shows that two positive charges or two
