Question

what is electric charge?

Answer 1

Answer:

Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field.

Explanation:

If we rub a glass rod with silk, the rod becomes charged. Similarly, an ebonite rod on being rubbed with cat-skin becomes charged. But, the charges of these two rods are of different types.

If a glass rod rubbed with silk is suspended by a thread and a second rubbed glass rod is brought near the first rod, then the suspended rod moves away from the second rod.

Similarly, if an ebonite rod rubbed with cat-skin is suspended and a second rubbed ebonite rod is brought near the first rod, then again the suspended rod moves away from the second rod.
