Question

Question 4 A negatively charged block of tron is placed in a region where there is a downward directed electric fueld E (red arrow). This electric field is generated by charges not shown in the figure. (a) How doe the excess negative charges distribute themselves in the presence of Er Circle the diagram that best describes the charge distribution in and/or on the tron block? Explatn your answer. (b) What must be the value of the electric field measured in the interior of the tron block? Explain your answer.

Explanation / Answer

Q1.

Ans- (B)

since negative charges will experience a force due to electric field in a direction opposite to electric field and positive charges in the the direction of field .

Q2.

Ans- Electric field inside the block, E'=applied electric field(E) - induced electric field inside the block due to polarization.
