Question

Dust is a mixture of different things, that is the reason that can posses charge.

Answer 1

Answer:

The first astronauts to land on the moon  observed the existence of thin layers of  dust hovering above the lunar surface. Like  there is no wind on the moon, it was understood that this  phenomenon was linked to the photoelectric effect  caused by sunlight: electrons are extracted from the

grain of dust from lunar soil when receiving energy  electromagnetic radiation from the sun and,  thus the grains become positively

loaded.

The same process also starts  electrons of the lunar surface, contributing to the  positive charge on the illuminated side of the  Thus, the electric field generated by the surface  of the moon makes the charged grains of sand suffer  electrical force upward by balancing your weight

Explanation:

Dust can be formed by small particles, smaller than 500 micrometers, but the nature can be so different from one place to another.

Answer 2

Answer:

Dust particles do not have charge in it, it is the charge of the substance that is attached to it that can flow the charge to the dust.

Explanation:

When the dust particle is attached to a charged substance it possess charge. The charge of the substance make the dust particles polarize to make it charged.

For example, when the dust particles sticks to a tv screen then it is not the dust charge that make it stick to the screen, it is the charge of the tv screen that make the particles attached to it.
