As we learned

 

Uniformly charged Non conducting sphere -

Suppose charge Q is uniformly distributed in the volume of a non conducting sphere of Radius R.

- wherein

 

 For non-conducting solid sphere E_{in}\alpha r

and E_{out}\alpha \frac{1}{r^{2}}

i.e. for r<R; E increases as r increases

and for R<r<¥; E decreases as r increases

 


Option 1)

Increases as r increases for r<R

 

 

 

Option 2)

 Decreases as r increases for O <r<\infty

Option 3)

Decreases as  r increases for R <r<\infty

Option 4)

both a and c
