Two concentric conducting thin spherical shells A andB having radii rA and `r8 (r_(8) gt r_(A))` are charged to `Q_(A)` and `- Q_(B)(|Q_(B)| gt |Q_(A)|)`. The electric field strength along a line passing through the centre varies with the distance x as :A. B. C. D. |

Answer» Correct Answer - C `{:(E_(A)=0,r lt r_(A)),(E_(A)=(KQ)/(r^(2)),r_(a)ltrlt r_(B)),(E_(B)=(KQ_(A))/(r^(2))-(KQ_(B))/(r^(2)),rgt r_(A)gt r_(B)):}` |
