Question
An infinite line of charge with charge density ?1 = -3.5 ?C/cm is aligned with the y-axis as shown.
3) A cylinder of radius a = 8.3 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.
4) Another infinite line of charge with charge density ?2 = 10.5 ?C/cm parallel to the y-axis is now added at x = 4.15 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 = -4.15cm.
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.

Just apply Gauss Law here, i.e Net Flux = close int(E.dS) = Net charge enclosed / permitivity
So we can apply this law or use the integration part to find flux.
By using the law, net charge enclosed is ?1 * h. Divide this by permitivity. There you go!
and increase your point.. there are too much of questions!!
