A conducting thick spherical shell of radii a and b ( b > a ) has been charged with uniform surface charge density - C / m^2 on the inner and + C / m^2 on the outer surfaces. Then
Options
- Athe net charge on the spherical shell is zero.
- Bthe radial electric field outside the shell is E= b^2 ₀ r^2
- Ca radial electric field E= (b^2-a^2 ) ₀ r^2 exists outside the shell.
- Dthere is a net electric charge in the cavity (i.e. in region r < a) equal to 4 (b^2-a^2 )
Correct answer
B. the radial electric field outside the shell is E= b^2 ₀ r^2
