Question

Problem 23.20 You've hung two very large sheets of plastic facing each other with distance d between them, as shown in the figure (Figure 1). By rubbing them with wool and silk, you've managed to give one sheet a uniform surface charge density Th no and the other a uniform surface charge density T2 +3no.

Explanation / Answer

for the electric field at the point 1

part A)

electric field at point 1 = electric field due to n1 + electric field due to n2

electric field at point 1 = -3n0/(2 * 0) + n0/(2 * 0)

electric field at point 1 = - n0/(0) i

part B)

at the point 2

electric field at point 2= electric field due to n1 + electric field due to n2

electric field at point 2 = -3n0/(2 * 0) - n0/(2 * 0)

electric field at point 2 = -2*n0/(0) i

part C)

at the point 3

electric field at point 3 = electric field due to n1 + electric field due to n2

electric field at point 3 = 3n0/(2 * 0) - n0/(2 * 0)

electric field at point 3 = n0/(0) i
