Question
An infinite line of charge with charge density ?1 = 0.6 ?C/cm is aligned with the y-axis as shown.
I got:
1) What is Ex(P), the value of the x-component of the electric field produced by by the line of charge at point P which is located at (x,y) = (a,0), where a = 7.5 cm? 14400000 N/C
2) What is Ey(P), the value of the y-component of the electric field produced by by the line of charge at point P which is located at (x,y) = (a,0), where a = 7.5 cm? 0 N/C
3) A cylinder of radius a = 7.5 cm and height h = 9.2 cm is aligned with its axis along the y-axis as shown. What is the total flux ? that passes through the cylindrical surface? Enter a positive number if the net flux leaves the cylinder and a negative number if the net flux enters the cylnder. 623728 N-m2/C
I need help with:
4) Another infinite line of charge with charge density ?2 = -1.8 ?C/cm parallel to the y-axis is now added at x = 3.75 cm as shown.
What is the new value for Ex(P), the x-component of the electric field at point P?
5) What is the total flux ? that now passes through the cylindrical surface? Enter a positive number if the net flux leaves the cylinder and a negative number if the net flux enters the cylnder.
6) The initial infinite line of charge is now moved so that it is parallel to the y-axis at x = -3.75cm.
What is the new value for Ex(P), the x-component of the electric field at point P?
7) What is the total flux ? that now passes through the cylindrical surface? Enter a positive number if the net flux leaves the cylinder and a negative number if the net flux enters the cylnder.

1)
For this question you want to use the equation for an infinite line of charge: E=2k(?/r)
Where k = 9x10^9.
Make sure you convert your numbers to ?1 = C/m and r = meters.
E = 2(9x10^9)(14400000()/(.075))
