Question

What do you mean by electric charge? How can you detect a charge on a body? Long answers type question.​

Answer 1

$\fbox\pink{A}\fbox\blue{n}\fbox\purple{s}\fbox\green{w}\fbox\red{e}\fbox\orange{r}$If a charged body (for example, ebonite rod) is touched to the metal disc of the gold-leaf electroscope, the metal strips of the electroscope gets charged by conduction. They repel each other and open up. In this way, we can detect whether an object is charged or not.

Answer 2

$\huge{\underline{\mathfrak{Answer:-}}}$

The GLE apparatus has a disk that conducts charge while it has gold leaves that move to show the nature of charge. For example, If we bring the charged body near its disc, the leaves further diverge, then body is negatively charged. However, if leaves collapse, charge G.L.E positively.

Electric charge, basic property of matter carried by some elementary particles that governs how the particles are affected by an electric or magnetic field. Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed.
