Before selecting answers to the following questions, draw your own diagram of this situation, showing all the fields and charge distributions requested.
Answer the following question by selecting either a direction (a-j) or an orientation of a polarized molecule (1-10) from the diagrams below.

Which of the following statements is correct?

Choose correct answers:

The polarization of a molecule located at D would be the same as the polarization of a molecule located at C

A molecule located at D would be polarized less than a molecule located at C

A molecule located at C would be not be polarized at all

A molecule located at D would be polarized more than a molecule located at C

Question Name: Polarization of a block of material due to dipole, 6

Before selecting answers to the following questions, draw your own diagram of this situation, showing all the fields and charge distributions requested.
Answer the following question by selecting either a direction (a-j) or an orientation of a polarized molecule (1-10) from the diagrams below.

Which of the arrows shown best indicates the direction of the electric field at location B, due only to the dipole?

Choose correct answers:

a

b

c

d

e

f

g

h

j

Explanation / Answer

1. eletric field due to the dipole is from left to right. The molecules are aligned along the field. and polarisation of the molecules is as in 1

2.A molecule located at D would be polarized more than a molecule located at C:

The fiedl strength diue to the dipole on its perpendicular bisector is proportional to 1/r^3, field strength at C is less compared to be and hence the molecule at C would be less polarised.

3. c. The reson is explained in 1.
