Answers

Answer:
Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
Explanation:
About 2500 years back a famous Unani philosopher Thales observed that when a material named Amber is rubbed with wool, it acquires the property of attracting light bodies such as pieces of paper, straws and many more.
However, this observation was not given any importance for about 2000 years. In 1600, Gilbert discovered that like Amber, several other materials such as glass, ebonite, sulphur and many more also on being rubbed attract light bodies.
Clearly, this property in the materials is developed due to rubbing, that is, by friction. On acquiring this property, the material is said to be "electrified" and the cause due to which this property is developed is called "frictional electricity".
