Three large but thin charged sheets are parallel to each other as shown in the figure . Sheet I has a total surface charge density of 7.9 nC/m^2, sheet II a charge of -3.3 nC/m^2, and sheet III a charge of 5.4 nC/m^2.
Figure:
----------------(I)
----------------(II)----------------(III)
Estimate the magnitude of the force per unit area on sheet I, II, and III, N/m^2.
**I do not know how to start**
Attempt: E=F/Q; Int(E) dA=Q/epsilon
2. E=F/Q; Int(E) dA=Q/epsilon; [tex]\sigma=Q/A[/tex]
3. I combined the above eq and got this:
\sigma*(\sigma)/(2epsilon)
