My Notes Ask Your Teach 15. -18 points PSE4 22. P.063 Three very large sheets are separated by equal distances of 20.0 cm (see the figure). The first and third sheets are very thin and nonconducting and have charge per unit area o of +9.00 uc/m2 and 9.00 uc/m2, respectively. The middle sheet is conducting but has no net charge. 20.0 cm- 20.0 cm (a) What is the electric field inside the middle sheet? N/C Direction-- Direction Direction- (b) what is the electric field between the left and middle sheets? -no direction N/C Direction-- to the left to the right (c) What is the electric field between the middle and right sheets? N/C --Direction-- v (d) What is the charge density on the surface of the middle sheet facing the left sheet? C/ (e) What is the charge density on the surface of the middle sheet facing the right sheet? C/

Explanation / Answer

a) inside a conductor , the electric field is zero under steady state

hence ,electric field is zero

hence , No direction

b)

as electric field is from positive to negative charge .

the direction of electric field will be to the right

c) the direction of electric field will be to the right

d)

charge density on left face = - charge density on the left sheet

charge density on left face = - 9 uC/m^2

charge density on left face = -9 *10^-6 C/m^2

e)

charge density on Right face = - charge density on the Right sheet

charge density on Right face = 9 uC/m^2

charge density on Right face = 9 *10^-6 C/m^2
