Answer #1

Statement 1:- The total charge on the inner surface of the small shell is -2q : False

Statement 2:-The radial component of the electric field in the region r > d is given by +4q/(4πε0r2): False because

total charge inside the Gaussian surface.


3. The total charge on the outer surface of the small shell is -6q. False


4. The radial component of the electric field in the region c < r < d is given by -2q/(4πε0r2). False

Because electric field inside a conductor is zero.


5. The total charge on the inner surface of the large shell is -6q. True
6. The total charge on the outer surface of the large shell is +2q. True
7. The radial component of the electric field in the region r < a is given by -2q/(4πε0r2). False

No charge is enclosed inside the Gaussian surface is zero.
