1. The problem statement, all variables and given/known data 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. 2. Relevant 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 3. 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!
