Question 2

Direction: In each of the Following questions, two statements are given. One is assertion and the other is reason. Examine the statement carefully and mark the correct answer according to the instruction given below

Assertion Dielectric polarization means formation of positive and negative charges inside the dielectric.
Reason Free electron are formed in this process.

Question 3

Direction: In each of the Following questions, two statements are given. One is assertion and the other is reason. Examine the statement carefully and mark the correct answer according to the instruction given below

Assertion Magnetic field interacts with a moving charge and not with a stationary charge.
Reason A moving charge produces a magnetic field.

Question 4

A 50 Hz AC current of crest value 1 A flows through the primary of a transformer. If the mutual inductance between the primary and secondary be 0.5 H, the crest voltage induced in the secondary is

Question 5

Direction: Each of these questions contains two statements. Assertion and Reason Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.

Assertion (A): A charge q is placed on a height h / 4 above the centre of a square of side b. The flux associated with the square is independent of side length.
Reason (R): Gauss’s law is independent of size of the Gaussian surface.
