Homework: Electric Potential Deadline: 100% until Sunday, February 16 at 11:59 PM Problems Print Assignment View Worked Emple Electric Potential Optional Potential of Infinite Sheets of Charge and Conducting Slab Interactive Example Spheres V jo Standard Exercise Potential of Concentric Sp Insulator and Conductor An infinite sheet of charge is located in the y-z plane at x = 0 and has uniform charge denisity 01 = 0.35 JC/m2. Another infinite sheet of charge with uniform charge density 02 = -0.22 C/m2 is located at x = c = 26 cm.. An uncharged infinite conducting slab is placed halfway in between these sheets (i.e., between IR X = 11 cm and x = 15 cm).

Answer 1

okay,

for part (4)

we need to break the path into two parts, one from P to R and then R to S

the first path will not contribute anything

so, for R to S

V = - E* d

where d = x = 11 cm

V = - 32200 * 0.11

V = - 3542.37 volts
