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

1. \(\oint_{s} \vec{E} \cdot d \vec{s} \neq 0\) on any surface.
2. \(\oint_{s} \vec{E} \cdot d \vec{s}=0\)if the charge is outside the surface.
3. \(\oint_{s} \vec{E} \cdot d \vec{s}=\frac{q}{\varepsilon_{0}}\) if charges of magnitude q were inside the surface.
4. both (2) and (3) are correct.

Given below are two statements: 
 
Assertion (A): Point charges \(q_{1}\) and \(q_{2}\) produce electric field of magnitude \(E_{1}\) and \(E_{2}\) at a point and potential \(V_{1}\) and \(V_{2}\) at the same point. The electric field due to both the charges at that point must be \(E_{1}+E_{2}.\)
Reason (R): The electric potential at that point due to both the charges must be \(V_{1}+V_{2}.\)
 
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
3. (A) is true but (R) is false.
4. (A) is false but (R) is true.

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
 
Assertion (A): If the electric field due to a dipole on its axis line at a distance r is E, then the electric field due to a dipole at the same distance at the equatorial line will be E/2.
Reason (R): Electric field due to dipole varies inversely as the square of the distance.
 
In light of the above statements choose the correct answer from the options given below:
 
1. Both (A) and (R) are true and (R) is the correct explanation of (A).
2. Both (A) and (R) are true but (R) is not the correct explanation of (A).
