Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
 

Assertion (A):	If a proton and an electron are placed in the same uniform electric field then they experience different accelerations.
Reason (R):	Electric force on a test charge is independent of its mass.

In the 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).
3.	(A) is true but (R) is false.
4.	(A) is false but (R) is true.

In the light of the above statements choose the correct answer from the options given below:
 

Given below are two statements: 

The figure shows some of the electric field lines corresponding to an electric field. The figure suggests: 

1. E_A > E_B > E_C

2. E_A = E_B = E_C

3. E_A = E_C > E_B

4. E_A = E_C < E_B

If \(\int_S E.ds = 0\) over a surface, then:

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

The electric field at a point is:
 

1. (a, b)

2. (b, d)

3. (c, d)

4. (a, d)

The electric flux through the surface,

(i)	(ii)
(iii)	(iv)

1. in figure (IV) is the largest

2. in figure (III) is the least

3. in figure (II) is same as in figure (III) but is smaller than figure (IV)

4. is the same for all figures

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