A) \[r<{{r}_{1}}\]
B) \[{{r}_{1}}<{{r}_{2}}\]
C) \[r<{{r}_{2}}\]
D) \[{{r}_{1}}<r<{{r}_{2}}\]
Correct Answer: D
Solution :
The electric field of a hollow spherical capacitor is localised in between inner and outer surfaces of the spherical conductor. Therefore, at point \[{{r}_{1}}<r<{{r}_{2}},\]the electric field will not be zero.
