Ncert Exercises & Solutions

If there were only one type of charge in the universe, then:

(a)	\(\oint_s {E} . {dS} \neq 0\) on any surface
(b)	\(\oint_s {E} . {dS} = 0\) if the charge is outside the surface.
(c)	\(\oint_s {E} . {dS}\) could not be defined.
(d)	\(\oint_s {E} . {dS}=\frac{q}{\epsilon_0}\) if charges of magnitude \(q\) were inside the surface.

Choose the correct statement(s):

1.	(a) and (d)	2.	(a) and (c)
3.	(b) and (d)	4.	(c) and (d)
