Answer 1

Answer: (A)

$A\to 2,B\to 4,C\to 3D\to 1$
A. Infinite plane sheet of charge $=\frac{\sigma }{2{\epsilon }_0}$
B. Infinite plane sheet of uniform thickness $=\frac{\sigma }{{\epsilon }_0}$
C. Non-conducting charged solid sphere at its surface $=\frac{R\rho }{3{\epsilon }_0}$
D. Non-conducting charged solid sphere at its centre $=0$.
