Question
An infinite line of charge with charge density ?1 = -1.5 ?C/cm is aligned with the y-axis as shown.
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 = 9.9 cm?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 = 9.9 cm?N/C
3)
A cylinder of radius a = 9.9 cm and height h = 9.1 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.
N-m2/C
4)
Another infinite line of charge with charge density ?2 = 4.5 ?C/cm parallel to the y-axis is now added at x = 4.95 cm as shown.
What is the new value for Ex(P), the x-component of the electric field at point P?
N/C
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. N-m2/C
6)
The initial infinite line of charge is now moved so that it is parallel to the y-axis at x = -4.95cm.
What is the new value for Ex(P), the x-component of the electric field at point P?
N/C
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.
