We have an infinite non-conducting sheet of negligible thickness carrying a uniform surface charge density – σ and next to it, an infinite parallel slab of thickness D with uniform volume charge density +ρ. All charges are fixed.
A
Magnitude of electric field at a distance h above the negatively charged sheet is 
B
Magnitude of electric field inside the slab at a distance h below the negatively charged sheet (h < D) is 
C
Magnitude of electric field at a distance h below the bottom of the slab is– 
D
Magnitude of electric field at a distance h below the bottom of the slab is 
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(a, b, d)
At a distance h above the sheet
E = E sheet + E slab
= 
At a distance h below the top surface of slab
E slab = 
E = E sheet + E slab = 
+ 
= 
At a distance h below the bottom surface of the slab =
