Ga small amber bead with a mass of 12.6 g and a charge of −0.646 µc is suspended in equilibrium above the center of a large, horizontal sheet of glass that has a uniform charge density on its surface. find the charge per unit area on the glass sheet (in µc/m2)

Explanation:

Given that,

Mass of the amber bead, m = 12.6 g = 0.0126 kg

Charge on the bead,

The electric field due to infinite large plastic sheet is given by :

At equilibrium, q E = m g

where

is the charge per unit area on the glass sheet.

So, the charge per unit area on the glass sheet is (). Hence, this is the required solution.

overcharge is the right answer system
