Homework Statement
Two infinite sheets with surface charge density σ1 and σ2, respectively, are oriented perpendicular to the x-axis. An infinite, conducting slab of thickness a is placed between the charged sheets as shown in the figure. The conducting plate has a net charge per unit area of σC.
Homework Equations
Calculate the x-component of the net electric field at x = 0.
(a) Ex = +7.85 × 105 V/m
(b) Ex = +6.22 × 105 V/m
(c) Ex = +5.65 × 105 V/m
(d) Ex = -2.67 × 105 V/m
(e) Ex = -3.85 × 105 V/m
QUESTION 15**
Calculate the surface charge density σR induced on the right hand face of the conducting plate.
(a) σR = +3.75 μC/m2
(b) σR = +2.00 μC/m2
(c) σR = -1.50. μC/m2
(d) σR = -3.00 μC/m2
(e) σR = -4.25 μC/m2
The Attempt at a Solution
14. for this number, i suppose left part of the conducting plate has the charge density -1.5. that gives the total E at x = 0 equal to 10. i use the formula E = sigma/2Eo = 10/(2*8.85) to get the answer C
15. I have no idea. I thought it was c, but the answer is B.
thank you so much!
