# Question: a uniform line charge of linear charge density 26...

###### Question details

A uniform line charge of linear charge density = 2.6 nC/m extends from x = 0 to x = 5 m. (a) What is the total charge? nC (b) Find the electric field on the x axis at x = 6 m. N/C (c) Find the electric field on the x axis at x = 8 m. N/C (d) Find the electric field on the x axis at x = 250 m. N/C (e) Find the field at x = 250 m, using the approximation that the charge is a point charge at the origin. N/C 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)
