A uniform line charge of linear charge density lambda 39

Question

Solve each part of given problem:

Problem: A uniform line charge of linear charge density lambda = 3.9 nC/m extends from x = 0 to x = 5 m.

Part A: What is the total charge?

Part B: Find the electric field on the x axis at x = 6 m.

_______N/C

Part C: Find the electric field on the x axis at x = 11 m.

_______N/C

Part D: Find the electric field on the x axis at x = 260 m.

_______N/C

Part E: Find the field at x = 260 m, using the approximation that the charge is a point charge at the origin.

_______N/C

Part F: Compare your result with that for the exact calculation in part (d).

____________ (field for the point charge divided by the field for the line charge)

Any help I can get on this problem is greatly appreciated! I'm not too familiar with this problem.
