List 1	List 2
Electric field at point P is	$\frac{2 K Q}{3}$
Electric potential at point P is $(V_{\infty} = 0)$	zero
Electric potential difference between A and B is	$\frac{K Q}{4}$
Electric field outside the shell B at distance 5m from center C is	$\frac{K Q}{6}$

A solid, uncharged conducting sphere of radius 3a contains a hollowed spherical region of radius a. A point charge +Q is placed at the common center of the spherse. Taking V =0 as r→∞, the potential at position r=2a from the center .of the spheres is :0kQ3akQ2a2kQ3a
