Homework Statement
Q1,Infinite uniform line charges of 5 nC/m lie along the x and y axes in free space. Find E at (a), P(0, 0 , 4); and (b), P (0 ,3 , 4)
Q2, Three infinite uniform sheets of charge are located in free space as follows: 3 nC/m2 at z= -4, 6 nC/m2 at z=1, -8 nC/m2 at z=4. Find E at point P (2,5,-5)
Homework Equations
E=ρL/2∏ε0ρ
Q1,I used this got: a), E=22.5z V/m
b), E=10.8y + 14.4z V/m
Q2, I used E= ρ/2ε0
The Attempt at a Solution
Q1, The right answer is a), E=45z V/m b), E = 10.8y+36.9z V/m
I really confused in this topic, So wish your guys help me. Thanks a lot.
