A non conducting sphere of radius a has a net charge +q uniformly distributed throughout its volume. A spherical conducting shell having inner and outer radii b and c and net charge −q is concentric with the sphere (see the figure).

Read the following statements
(i) The electric field at a distance r from the center of the sphere for r<a is 
(ii) The electric field at distance r for A<r<b is 0
(iii) The electric field at distance r for b<r<c is 0
(iv) The charge on the inner surface of the spherical shell is −q
(v) The charge on the outer surface of the spherical shell is +q
Which of the above statements are true?
  • a)
    (i), (ii) and (v)
  • b)
    (i), (iii) and (iv)
  • c)
    (i), (ii) and (iv)
  • d)
    (ii), (iii) and (v)
Correct answer is option 'B'. Can you explain this answer?

A non conducting sphere of radius a has a net charge +q uniformly dist...
Correct option is B)
Solution
Let 
 is the inner surface charge.
then, 
 such that
Electric field inside
the conductor should
be zero ( r > b and r < e)
so in the arbitrary
Gaussian surface
Electric flux = 
So, 
 and 
(i) Electric field for r < a ia,
As a charge is uniformly distributed
q inside = 
So, 
(ii) Electric field for a < r < b,
(iii) Electric field for b < r < c
As told earlier, E = 0
(iv) Electric field for c < r
Option - B is correct.
