Answer:
The electric field at x = 3L is 166.67 N/C
Solution:
As per the question:
The uniform line charge density on the x-axis for x, 0< x< L is
Total charge, Q = 7 nC =
At x = 2L,
Electric field,
Coulomb constant, K =
Now, we know that:
Also the line charge density:
Thus
Q =
Now, for small element:
Integrating both the sides from x = L to x = 2L
Similarly,
For the field in between the range 2L< x < 3L:
Now,
If at x = 2L,
Then at x = 3L:
