Answer:

[tex]Charge_{density}=2.2125*10^{-6}C/m^{2}[/tex]

Explanation:

Given data

Electric Field E=2.5×10⁵ N/C

To find

Charge Density

Solution

From definition of charge density we know that:

Charge Density=Electric field×Permttivity

Where Permttivity ∈₀=8.85×10⁻¹²C²/N.m²

[tex]Charge_{density}=(2.5*10^{5}N/C)*(8.85*10^{-12}C^{2}/N.m^{2})\\ Charge_{density}=2.2125*10^{-6}C/m^{2}[/tex]
