A charge of 4 nC is placed uniformly on a square sheet of nonconducting material

Question

A charge of 4 nC is placed uniformly on a square sheet of nonconducting material of side 21 cm in the yz plane.

(a) What is the surface charge density nC/m2
(b) What is the magnitude of the electric field to the right (x > 0) of the sheet kN/C
To the left (x < 0) of the sheet kN/C
(c) The same charge is placed on a square conducting slab of side 21 cm and thickness 0.11 mm. What is the surface charge density Assume that the charge distributes itself uniformly on the large square surfaces nC/m2
(d) What is the magnitude of the electric field to the right (x > 0) of the right face of the slab kN/C
To the left (x < 0) of the left face of the slab kN/C

Explanation / Answer

136.05nC/m2 15.37 kN/C 67.39 nC/m2 7.61 kN/C 7.61 kN/C
