Fig. 1.11 shows the electric field lines around three-point charges A, B and C.

(b) Which charge has the largest magnitude? Why?
(c) In which region or regions of the picture could the electric field be zero? Justify your answer.
(i) near A, (ii) near B, (iii) near C, (iv) nowhere.



 

Answers (1)

i) A and C are positive charges as the electric field lines are protruding out of these two charges.

ii) Charge C has the largest magnitude as it has the greatest number of electric field lines coming out.

iii) The neutral region is in between the charges A and C. Charges C is a stronger charge; therefore the neutral point naturally lies near to A (charge A is a weak charge).
