Try again. shell 2 The figure shows two nonconducting spherical shells fixed in place. Shell 1 has uniform surface charge density +5.8 C/m2 on its outer surface and radius 3.6 cm has uniform surface charge density 14.2 uC/m2 on its outer surface and radius 1.9 cm; the shell centers are separated by L -11.4 cm.

Explanation / Answer

x = 2.1 cm,

this point is inside shell 1:

so due to shell , E1 = 0

due to other shell,

E = k Q2 / (0.114 - 0.021)^2

Q2 = sigma (4 pi r^2)

= (4.2 x 10^-6) (4 x pi x 0.019^2)

= 19.1 x 10^-9 C  

E = (9 x 10^9 x 19.1 x 10^-9) / (0.093)^2

E = 19726 N/C ...Ans
