A series of six infinite charged sheets are placed on positive x-axis at a distance of 5 pm
with each other. Consider the first sheet is placed at x=0. The third sheet is grounded.
The Electric field is $*10' NC and is uniform in the region Calculate the potential at
the first sheet the last sheet respectively
in) -5V and 75V
(b) 5V and - 75
(c) -7.5V and 5V

Answer:
Hey mate here is your answer
Explanation:
Electric field due to the charged sheet is E=
2ε
0
σ
Away from the if the charge is positive and towards the sheet if the charge is negative.
Let the sheet are A,B,C
Electric field at a point in between the sheets B and C is :
Electric field due to A is E=
2ε
0
σ
towards A
electric field due to B towards B is 2(E=
2ε
0
σ
)
Therefore, electric field due toC is E=
2ε
0
σ
away from C
Net electric field
=
2ε
0
σ
(1+2+1)=4(
2ε
0
σ
)
=
ε
0
2σ
And along the z-axis along unit vector
k
^
=
ε
0
2σ
k
^
Hence, Option A is the correct answer
