Question

The conducting box in the figure (Figure 1) has been given an excess negative charge. The surface density of excess electrons at the center of the top surface is 2.30 times 10^10 electrons/m^2. What is the electric field strength E_1 at point 1? Express your answer as an integer and include the appropriate units. What is the electric field strength E_2 at point 2? Express your answer as an integer and include the appropriate units. What is the electric field strength E_3 at point 3? Express your answer as an integer and include the appropriate units.

Explanation / Answer

PartA) Electric field E = 2* sigma /2eo

= 2* (1.6e-19*2.30e10)/(2*8.85e-12)

= 416 N/C

PartB) E = 0

as electric field inside a conductor is zero.

PartC) It will be cancelled by both plates acting in opposite directions.

E =0
