Question

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
(d) 7.5V and - 5V​

Answer 1

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
