he electric field lines surrounding three charges are shown in the figure below. The center charge is q2 =-14.2 pC. E field lines 91 03 (a) What are the signs of q? and q3? q1 Select…? q3-Select--.? (b) Find q1 ?? HC (c) Find q3 HC
Solution
The electric field lines originating from q1 and q3 so they are positive charges
q1 ( posiitve), q3 ( positive)
(b)
from figure,8 lines leaving from q1,q3 and q2 has16 lines entering it so q1 =q2/2
q2 =-14.2 ?C
so q1 =q2/2
q1 =-7.1 ?C
since q1 is positive q1 = 7.1 ?C
(c)
q3 =q2/2
q3 =-7.1 ?C
since q3 is positive q3 = 7.1 ?C
