Consider two concentric conducting spherical shell with inner and outer radiia,b,canddas shown in the figure. Both the shell are givenQamount of positive charges.The electric field in different regions area)b)c)d)Correct answer is option 'D'. Can you explain this answer?

Question

Answer

For r < a, applying Gauss’s law.

∴ q = 0
Also since shells are conducting

For b < r < c by Gauss’s law

For r > d, applying Gauss’s law, we get
