Homework Statement
Ok.Then there was a question
If r is distance measured from center of a charged shell and R is it's radius then the graph which may correctly represent variations of electric field is
Homework Equations
E vs R graph
The Attempt at a Solution
The answer is given to be A but I want to ask why not C ?There are two cases
1-shell with all charges on surface in this case E for r<R is zero so Option A fits in
2-Shell with charges throughout the volume(volumetric distribution)
In which E for r<R has formula
E=ρr/3ε0 (ρ=CHARGE PER UNIT VOLUME)
it is clear E ∝ r
For this C seems correct.And the question does not clarify which type of shell(type 1 or type 2) is to be referred
So why answer is A?Why it can't be C?
