Question

The electric field E is measured at a point P(0,0,d) generated due to various charge distributions and the dependence of E on d is found to be different for different charge distributions. List-I contains different relations between E and d. List-II describes different electric charge distributions, along with their locations. Match the functions in List-I with the related charge distributions in List-II
                                      

List–I	List–II
P. E is indpendent of d	1. A point charge Q at the origin
Q. $E\propto \frac{1}{d}$	2. A small dipole with point charges Q at (0,0,$\iota$) and – Q at (0,0, – $\iota$). Take 2$\iota$ << d
R. $E\propto \frac{1}{d^2}$	3. An infinite line charge coincident with the x-axis, with uniform linear charge density $\lambda$
S. $E\propto \frac{1}{d^3}$	4. Two infinite wires carrying uniform linear Charge density parallel to the x - axis. The one along (y = 0, z = $\iota$) has a charge density + $\lambda$ and the one along (y = 0, z = –$\iota$ ) has a charge density – $\lambda$. Take 2 $\iota$<< d
	5. Infinite plane charge coincident with the xy-plane with uniform surface charge density
