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 centre of the sphere for r lt a is `1/(4piepsilon_(0))(qr)/a^(3)`
(ii) The electric field at distance r for a lt r lt b is 0
(iii) The electric field at distance r for b lt r lt 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. (ii), (iii) and (iv)
D. (ii), (iii) and (v)
